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.

The M62001 to M62008 carry out voltage detection in two-steps and have two 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 to M62004) and hold type (M62005 to M62008).

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.
