LOW POWER 2 OUTPUT SYSTEM RESET IC SERIES

DESCRIPTION

The M62001~8 are semiconductor integrated circuits whose optimum use is for the detection of the rise and fall in the power supply to a microcomputer system in order to reset or release the microcomputer system.

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).

FEATURES

•Bi-CMOS process realizes a configuration of low current dissipating circuits.

Circuit current

Icc=5µA(Typ.,normal mode,Vcc=5.0V) Icc=1µA(Typ.,backup mode,Vcc=2.5V)

•Two-step detection of supply voltage

Detection voltage in normal mode (2 types) Vs=4.45V/4.25V(Typ.)

Detection voltage in backup mode VBATT=2.15V(Typ.)

•Two outputs

Reset output (RESET):Output of compulsive reset signal Interruption output(INT):Output of interruption signal

•Two types of output forms:CMOS and open drain •Two types of interruption output (INT) signals

Pulse type	(M62001~M62004)
Hold type	(M62005~M62008)
•Two types of outline packages
5-pin plastic SIP		(single in-line package)
8-pin plastic SOP		(mini flat package)

•Output based on RAM backup mode (See the timing chart.)
