The ]M62001~8 carry out voltage detection in 2 steps and have 2 output pins.As BI-CMOS process and low power dissipating circuits are employed,they output optimum signals through each output pin to a system that requires RAM backup, As output signals interruption(INT} and compulsive reset((RESET) signals are available. The interruption signal(INT} is used to alter the microcomputer from normal mode to backup mode and vice versa. these output signals are classified into pulse type(M62001~M62004) and hold type (M62005~M62008).

The M62001-M62008 are ICs thatin such memory backup operation,monitor in 2 steps each voltage on the Voo line. MAIN POWER NG oe SUPPLY BACKUP RESET RESET POWER M62004 SUPPLY MICROCOMPUTER SYSTEM The ICs have an intelligent sequence such as substantial hysteresis action of RESET toward normal state at restoration of supply voltage,as well as 2-step detection in low power dissipation mode. OPERATION IN DETAIL 1.Two Step Detection The IGs perfonn 2-step detection of supply voltage and have 2 output pins (NT and RESET).Although they have 2 comparators for 2-step detection, they differ significantly from such that are simply provided with independent detectors,because the RESET output signal is dependent at power-up and the like upon the INT output signal. 2. INT output (Detection of 4.45V and 4.25V) The INT output at the power-up of supply voltage detects VSH (4.45 Vi4 25Vito inform the microcomputer system of the fact that the supply voltage has reached its normal level When the supply voltage drops from its normal level to Vs_(4 45 Wi 25Vjan interruption signal is output to alter the microcomputer system into RAM backup mode. The microcomputer at this point enters sleep state and secures memory by a stop command issued by the interruption signal. These detection voltage ,VSH the rise,and VSL the fall,of supply voltage have a 100-mV hysteresis voltage between themselves. VSH-VSL=100(mV) INT OUTPUT VOLTAGE VS.

When powering up, RESET is kept at low level until the supply voltage reaches VSH_If the supply voltage rises to VSH RESET is setto high level.By inserting a capacitor between the Cd pin and GND. it is possible to produce a desired delay time (td}.To set a delay time,equation below is used. td=1.52X10 XCdisec} Once the supply voltage has exceeded VSH and the RESET outputis set to high level, RESET maintains the high level until the supply voltage drops to VBATT When the supply voltage drops to VBATT,RESET goes low thereby resetting and initializing the microcomputer. The RESET output has a large hysteresis voltage of approximately 2V between the rise in supply voltage at power- up and its fall. RESET OUTPUT VOLTAGE VS.
