Monolithic Linear IC
LA5623M
Combination System Reset IC
Overview
The LA5623M is a combination reset IC that provides two
reset functions. The first, reset 1, detects the input voltage
and applies a reset to the CPU system and other logic
systems. The second, reset 2, detects the power supply
voltage when the power is turned on or off, and applies a
reset to the CPU system and other logic systems. This
latter function allows the reset time to be adjusted from
two external pins.

Features
鈥?Reset circuit (output 1) that detects the input voltage and
provides a delay time of 200 碌s.
鈥?System reset circuit (output 2) that provides a switchable
delay time of 25, 50, 100, or 200 ms.
鈥?Low operating limit voltage
鈥?Both reset 1 and reset 2 have hysteresis characteristics.
