FM1233

Precision Reset Generator Circuit

General Description

Features

The FM1233 features comprehensive reset generation for

microcontroller/microprocessorbasedsystems. IfthesystemV_CC

voltage level is determined to be in an out-of-tolerance state, the

device automatically generates a low-going reset signal. The

reset signal is held in the active state (low) for a specified duration

(minimum 140 ms) after the V_CCreturns to an in-tolerance state.

I Automaticresetgenerationonpower-up

I Minimum 140 ms reset pulse — compatible with other similar

1233 class devices

I Other reset pulse choices available: 32 - 256 ms

I Choice of commercial and extended temperature ranges

I Choice of Reset Thresholds: 4.63V, 4.38V, 4.00V, 3.08V,

2.93V, 2.63V

The FM1233 also allows an external reset to be connected to the

reset pin without adding aditional debounce logic or extra pins.

I Package available: SOT-23

This device is fabricated using CMOS technology. This device is

available in the SOT-23 package.
