| Order this document by MC33193/D MC33193 Advance Information Automotive Direction Indicator The MC33193 is a new generation industry standard UAA1041 "Flasher". It has been developed for enhanced EMI sensitivity, system reliability, and improved wiring simplification. The MC33193 is pin compatible with the UAA1041 and UAA1041B in the standard application configuration as shown in Figure 9, without lamp short circuit detection and using a 20 m shunt resistor. The MC33193 has a standby mode of operation requiring very low standby supply current and can be directly connected to the vehicle's battery. It includes an RF filter on the Fault detection pin (Pin 7) for EMI purposes. Fault detection thresholds are reduced relative to those of the UAA1041, allowing a lower shunt resistance value (20 m) to be used. * Pin Compatible with the UAA1041 AUTOMOTIVE DIRECTION INDICATOR SEMICONDUCTOR TECHNICAL DATA 8 1 * * * * * * Defective Lamp Detection Threshold RF Filter for EMI Purposes Load Dump Protection Double Battery Capability for Jump Start Protection Internal Free Wheeling Diode Protection Low Standby Current Mode D SUFFIX PLASTIC PACKAGE CASE 751 (SO-8) 8 1 P SUFFIX PLASTIC PACKAGE CASE 626 Simplified Block Diagram PIN CONNECTIONS 1 SW2 SW1 Starter 8 VSS 1 VCC 2 Relay 3 Oscillator 4 5 Oscillator 6 Enable 7 Fault Detector 8 Starter (Top View) 2 24 V 33 V Detector Reference Voltage RF Filter 7 3 Relay Driver Lamp Fault Detector 6 4 Oscillator 5 ORDERING INFORMATION Device MC33193D Operating Temperature Range TA = -40 to +125C Package SO-8 DIP-8 Rev 0 This device contains 60 active transistors.

It is a new generation industry standard UAA1041 "Flasher". It consists of the following functions: * * * * * * Supply and Protections On-Chip Relay Driver Oscillator Starter Functions Lamp Fault Detector with Internal RF Filter Standby Mode Oscillator The device uses a sawtooth oscillator (Figure 1). The frequency is determined by the external components C1 and R1. In the normal operating mode, the flashing frequency is: Fn = 1/R1*C1*Kn. With a defective (open) 21 W lamp (Figure 2), the flashing frequency changes to: Fn = 2.2*Fn. The typical first flash delay (the time between the moment when the indicator switch is closed and the first lamp flash occurs) is: t1 = K1*R1*C1 The fault detection delay is from the time relay R1 is on and fault detection is enabled. Where a 21 W lamp opens, the delay is expressed as: t2 = K2*R1*C1 Starter Pin 8 is connected through a 3.3 k resistor to the flashing lamp. Pin 8 is the input to the Starter function and senses the use of S1 by sensing ground through the lamp (Figures 9 and 10). Lamp Fault Detector with Internal RF Filter A Lamp defect is sensed by the lamp fault detector's monitoring of the voltage developed across the external shunt resistor RS via the RF filter. The RS voltage drop is compared to a Vbat dependent internal reference voltage (Vref) to validate the comparison over the full battery voltage range. A detected fault causes the oscillator to change frequency (Figure 2). Standby Mode When the ignition key and warning switches are open; Enable is in a low state and the internal switches, SW1 and SW2, are open and no current passes through the circuit. In this condition, the device's current consumption is zero (ICC = 0). When ignition key and warning switches are closed; Enable is in a high state with SW1 and SW2 being closed and the circuit is powered on. Supply and Protection Systems Pin 1 is connected to ground via resistor R3 which limits the current in the event of any high voltage transients. Pin 2 (VCC) is the positive supply and may be connected directly to the vehicle's battery voltage. Overvoltage and Double Battery Protection: When the applied VCC to VSS voltage is greater than 22 V, the overvoltage detector circuit turns the relay driver off. Both the device and the lamps are protected if two 12 V batteries are connected in series and used to jump start the vehicle. Load Dump Overvoltage Protection: A 29 V overvoltage detector protects the circuits against high voltage transients due to load dumps and other low energy spikes. The relay driver is automatically turned on whenever the VCC to VSS voltage is greater than 34 V. Overvoltage Protection, High Voltage Transients: The Enable and the Starter pins are protected against positive and negative transients by internal on-chip diodes. On-Chip Relay Driver The device directly drives the flasher relay. The output structure is an Emitter of an NPN transistor. It contains the free wheeling diode circuitry necessary to protect the device whenever the relay is switched off. MOTOROLA ANALOG IC DEVICE DATA 3 MC33193 MAIN DIFFERENCES BETWEEN UAA1041B & MC33193 The MC33193 is pin compatible with the UAA1041. Supply Current Supply current is more stable on the MC33193 when the device is in "on" or "off" state. In "on" state the supply current is only 40% higher than when in the "off" state, as compared to a ratio of 3 times for the UAA1041. This results in a lower voltage drop across the ground resistor R3 (see On-Chip Relay Driver). Short Circuit Detection The MC33193 has no short circuit detection. Standby Mode (Pin 6) The UAA1041 has no standby mode. Pin 6 is used as an Enable/Disable for the short circuit detection. The MC33193 uses Pin 6 to set the device in standby mode. If Pin 6 is connected to ground, the MC33193 is in the standby mode. In this mode, standby current is very low and Pin 8's starter resistor R2 and a 2.0 k internal resistor are switched off. As soon as Pin 6 is at a high level (typical threshold = 2Vbe) the device becomes active. In the application, the MC33193 can be connected directly to the battery and awakened whenever Pin 6 is connected to the vehicle's battery by way of a protection resistor and the ignition key switch. Lamp Defect Detection (Pin 7) The UAA1041 operates with a 30 m shunt resistor to sense the lamp current. It's lamp defect detection threshold of Pin 7 is typically 85 mV. The MC33193 is designed to operate with 20 m shunt resistor and at a reduced threshold of 50 mV. This reduces power generation in the flasher module. In addition, the MC33193 incorporates an RF filter to enhance RFI immunity. Load Dump and Overvoltage Behavior The UAA1041 and MC33193 both behave the same in this regard. Both have double battery detection and lamp turn-off protection in the event of a jump start. During load dump, both devices are protected by an internal 30 V zener diode with the relay activated during a load dump. Relay Driver Drive capability of both devices is the same. Free wheeling diode protection is internal to both devices. The free wheeling voltage is 2Vbe for the UAA1041 and 3Vbe for the MC33193. This results in a higher clamp voltage across the relay and thus in a faster turn-off. In addition, the lower "on" state supply current is lower on the MC33193 and thus the voltage drop across the ground resistor R3 is reduced. This results in an even higher clamp voltage across the relay. Oscillator Phase The oscillator phase is opposite on the MC33193 as compared to the UAA1041. The Oscillator voltage is falling during "on" state and rising during "off" state for the MC33193. 4 MOTOROLA ANALOG IC DEVICE DATA MC33193 Figure 4.
