Description

The M62001 to M62008 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.

Features

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

Circuit current

ICC = 5 μA (Typ, normal mode, VCC = 5.0 V)

ICC = 1 μA (Typ, backup mode, VCC = 2.5 V)

? Two-step detection of supply voltage

Detection voltage in normal mode (2 types)

VS = 4.45 V/4.25 V (Typ)

Detection voltage in backup mode

VBATT = 2.15 V (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 to M62004)

Hold type (M62005 to 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)

Application

? Prevention of errors in microcomputer system in electronic equipment that requires RAM backup, such as office, industrial, and home-use equipment.
