s FUNCTIONAL DESCRIPTION
1. Power Control
(1) Reference voltage This circuit uses the voltage generated by VB1 terminal (pin 28) to produce a temperature compensated reference voltage (1.23 V typ.) for power control and uses this reference voltage on power control. (2) Baseband regulator (BBREG1) This regulator uses the reference voltage to produce an output voltage (2.85V typ.) at OUT1 terminal (pin 75). Power can be drawn from OUT1 terminal for external use, up to a maximum load current of 110 mA. (3) Baseband regulator (BBREG2) This regulator uses the reference voltage to produce an output voltage (2.85 V typ.) at OUT2 terminal (OUT21 terminal (pin 72), OUT2-2 terminal (pin73)). Power can be drawn from OUT2 terminal for external use, up to a maximum load current of 150 mA. (4) Baseband regulator (BBREG3) This regulator uses the reference voltage to produce an output voltage (2.85V typ.) at OUT3 terminal (pin 71). Power can be drawn from OUT3 terminal for external use, up to a maximum load current of 60mA. (5) Battery backup regulator (BATTREG) This regulator uses the reference voltage to produce an output voltage (3.1V typ.) at BATTOUT terminal (pin 69). (6) Vibrator drive circuit (VIBREG) This circuit uses the reference voltage to produce an output voltage (1.5V typ.) at VIBREG terminal (VIBREG1 terminal (pin 78), VIBREG-2 terminal (pin 79)). Power can be drawn from VIBREG terminal for external use, up to a maximum load current of 200mA. (7) RF regulator (RFREG1) This regulator uses the reference voltage to produce an output voltage (2.85V typ.) at RFOUT1 terminal (pin 42) when an "H" level signal is input at the RFCTL1 terminal (pin 41). Power can be drawn from RFOUT1 terminal for external use, up to a maximum load current of 10mA. (8) RF regulator (RFREG2) This regulator uses the reference voltage to produce an output voltage (2.85V typ.) at RFOUT2 terminal (pin 40) when an "H" level signal is input at the RFCTL2 terminal (pin 39). Power can be drawn from RFOUT2 terminal for external use, up to a maximum load current of 20mA. (9) RF regulator (RFREG3) This regulator uses the reference voltage to produce an output voltage (2.85V typ.) at RFOUT3 terminal (pin 38) when an "H" level signal is input at the RFCTL3 terminal (pin 37). Power can be drawn from RFOUT3 terminal for external use, up to a maximum load current of 20mA.
27
MB3892
(10) RF regulator (RFREG4) This regulator uses the reference voltage to produce an output voltage (2.85V typ.) at RFOUT4 terminal (pin 35) when an "H" level signal is input at the RFCTL4 terminal (pin 36). Power can be drawn from RFOUT4 terminal for external use, up to a maximum load current of 60mA. (11) RF regulator (RFREG5) This regulator uses the reference voltage to produce an output voltage (2.85V typ.) at RFOUT5 terminal (RFOUT5-1 terminal (pin 30), RFOUT5-2 terminal (pin 29)) when an "H" level signal is input at the RFCTL5 terminal (pin 31). Power can be drawn from RFOUT5 terminal for external use, up to a maximum load current of 200mA. (12) RF regulator (RFREG6) This regulator uses the reference voltage to produce an output voltage (2.85V typ.) at RFOUT6 terminal (pin 33) when an "H" level signal is input at the RFCTL6 terminal (pin 32). Power can be drawn from RFOUT6 terminal for external use, up to a maximum load current of 50mA. (13) Variable bias regulator This regulator uses the voltage generated by VREGIN terminal (pin 67) to produce an amplified output voltage at VREGOUT terminal (pin 68). Power can be drawn from VREGOUT terminal for external use, up to a maximum load current of 10mA. (14) D/A converter D/A1 to D/A3 converter process 8 bit input signal and D/A4 converter processes 10 bit input signal. This converter generates an output voltage (0.5 to 2.5V ) at D/AOUT1 terminal (pin 63) to D/AOUT4 terminal (pin 60) according to the signal from serial control. (15) Power-on reset When the OUT1 terminal (pin 75) voltage exceeds 2.75V(typ.) , after a delay interval set by a capacitor (0.1 F typ.) connected to the CTP terminal (pin 76) , the RESET terminal (pin 77) voltage becomes "H" level from "L" level and the reset signal is canceled. When the OUT1 terminal voltage falls below 2.685V (typ.), the RESET terminal voltage becomes "L" level from "H" level and the reset signal is dispatched. (refer to "sPOWER-ON RESET TIMING DIAGRAM", "sSETTING OF HOLD TIME FOR POWER-ON RESET".) (16) Battery voltage detect This function is to observe the battery voltage. When the VB4 terminal (pin 58) voltage exceeds 3.05V (typ.), the 3VDET terminal (pin 56) voltage goes to "H" level and when the VB4 terminal voltage falls below 2.85V (typ.), the 3VDET terminal goes to "L" level. (refer to sBATTERY VOLTAGE DETECTOR)

The optional gain can be set by the connection of feedback resistor from FB terminal (pin 20) to OUTA terminal (pin 25) and the connection of input resistor to FB terminal. (2) Loudspeaker Amp. This is the BTL output type Amp. driving speaker directly. When the output power is 260mW typ. (at 8), the serial control processes the on/off control. The optional gain can be set by the connection of feedback resistor from FB terminal (pin 20) to SPOUTA terminal (pin 22) and the connection of input resistor to FB terminal.
3. Sounder
Three low-saturation output transistors are built in for buzzer drive. When the signal from serial control is "H" level and IN1 terminal (pin 10) voltage is "H" level, the V01 terminal (pin 16) voltage is 0.3V (typ.). When IN2 terminal (pin 11) voltage and IN3 terminal (pin 12) voltage are "H" level, the V02 terminal (pin 14) voltage and V03 terminal (pin 13) voltage are also 0.3V (typ.).
4. LED drive
The LEDO1 terminal (pin 2) voltage and LEDO2 terminal (pin 4) voltage is 0.2V (typ.), when the signal from serial control is "H" level. When the signal from charge control is "H" level, the LEDR terminal (pin 1) voltage is 0.2V (typ.).
5. Charge control
(1) Charge control The main charge is started by the signal from serial control indicates preliminary charge is finished. According to the voltage level at CHGV terminal (pin 49) generated by microprocessor on the microprocessor operation, the charge current is controlled by adjusting gate voltage from outside FET. (2) Charge current detector The charge current detector sensitivity (gain) can be switched by the signal from serial control. The VBH terminal (pin 46) voltage and VB4 terminal voltage (pin 58) are detected and CHGI terminal (pin 47) voltage is generated. (3) Preliminary charge circuit When the battery voltage is low, the charge is controlled until the microprocessor starts the operation. Before the battery voltage reaches 2.6V (typ.), 50mA (typ.) is used for the charge and before 4V (typ.), 100mA (typ.) is used. (4) External power supply detector This function is to detect if the case is attached to the battery charger. When the case is attached to the battery charger, EXTVCC terminal (pin 52) voltage is "H" level and generate "L" level voltage at CHGDET terminal (pin 51). When the case is not attached to the battery charger, EXTVCC terminal voltage is "L" level and generate "H" level voltage at CHGDET terminal. 29
