| CS8240 500 mA High Side (PNP) Driver with On-Chip Flyback Diode The CS8240 is a fast, PNP high side driver capable of delivering up to 500 mA into a resistive or inductive load in harsh automotive or industrial environments. An internal flyback diode clamp is incorporated for inductive loads. The input (VIN) is TTL and CMOS compatible and has hysteresis to minimize the effects of noise. When the input is high, the output is on. When the input is low, the output is off and the supply voltage quiescent current is very low (< 1.0 A, typ). For device protection, the CS8240 incorporates thermal shutdown, short circuit current limiting, overvoltage shutdown, and reverse battery protection. The CS8240 can withstand supply voltage transients of 60 V (min) and -50 V. The CS8240 is available in an overmolded 5 lead TO-220 package and is a competitive replacement for the LM-1921, LM-1951, LM-1952, MC-3399, and L-9350.

Flyback Clamp Characteristics Figure 7. IIN vs. VIN CIRCUIT DESCRIPTION Input Stage The input stage is a self biased band gap based circuit with a positive going trip point of 1.45 V (typ) and a negative going trip point of 1.20 V (typ) (250 mV of hysteresis). When the input voltage is below the positive trip point, the quiescent current of the supply voltage line is less than 1.0 A, (typ). When the input voltage exceeds the positive trip point (1.45 V, typ), the input stage "wakes up" the rest of the CS8240 circuitry and turns on the output stage. Output Stage the given output current. The base drive of the PNP is the dominant component of the quiescent current of the CS8240 and is dependent on the level of output current. Short circuit protection (1.1 A, typ) is also incorporated in the output stage. Protection Circuitry The output stage is built around a high current PNP output transistor. A control amplifier monitors the saturation voltage of the output PNP and maintains a balance of low saturation voltage and minimum base drive to the PNP for In addition to the short circuit protection mentioned above, the CS8240 also incorporates a thermal shutdown circuit (165C, typ) and a high voltage shutdown circuit (33 V, typ), both of which cut off the drive to the PNP output transistor when excessive current is drawn. Inherent in the design of the CS8240 is transient protection to +60 V and -50 V on the supply line. The CS8240 is ESD protected in excess of 2.0 kV (Human Body Model). http://onsemi.com 4 CS8240 TYPICAL APPLICATION CIRCUITS VCC* 0.1 F 1 2 CS8240 5.0 V 0V 5 3 Figure 8.
