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