Low battery detection circuit The PC-E500 is equipped with the low battery detection circuit. The operations of the circuit are described below. (Part location numbers may differ from those in the actual circuit diagram.) When input voltage VIN exceeds the detection voltage VD, the output of the voltage detection IC [LBIC(MN1280)] is driven from Low to High. When VIN falls under VD, the output is driven from High to Low. The LBIC (MN1280) detects both the CAU level and the STOP level by dividing the voltage applied to the input terminal (2 pin) with R1 and R2 and by turning on/off R2 with CAU signal of G-A. When the power voltage falls under the CAU level, as shown in Fig. 3, the BATT symbol lights up. When the power voltage falls further under the STOP level, the symbol goes off. For CAU level detection, the CPU E3 it turned on (low level) and the CPU IRQ terminal state is observed. (If the IRQ is at Low level, the symbol lights up.) When the CAU level is detected, the CPU E3 terminal is turned off (high impedance). (When the CPU E3 terminal is turned off, resistor division is not performed and the voltage at LBIC 2 pin increases, driving the output from Low to High.) The CPU IRQ terminal state is checked again to detect the STOP level After the STOP level is detected, the ON key and the RESET key be- come ineffective.
