LM3712

Microprocessor Supervisory Circuits with Separate

Watchdog Timer Output, Power Fail Input and Manual

Reset

General Description

Features

The LM3712 series of microprocessor supervisory circuits

provide the maximum flexibility for monitoring power supplies

and battery controlled functions in systems without backup

batteries. The LM3712 series are available in a 9-bump micro

SMD package.

Standard Reset Threshold voltage: 3.08V

■

Custom Reset Threshold voltages: For other voltages

between 2.2V and 5.0V in 10mV increments, contact

National Semiconductor Corp.

No external components required

■

Built-in features include the following:

Manual-Reset input

Reset: Reset is asserted during power-up, power-down, and

brownout conditions. RESET is guaranteed down to V_CCof

1.0V.

RESET output

Precision supply voltage monitor

Factory programmable Reset and Watchdog Timeout

Delays

■

Manual Reset Input: An input that asserts reset when pulled

low.

Separate Watchdog output

■

Power-Fail Input: A 1.225V threshold detector for power fail

warning, or to monitor a power supply other than V_CC

Separate Power Fail comparator

Available in micro SMD package for minimum footprint

Watchdog Timer: The WDI (Watchdog Input) monitors one of

the µP's output lines for activity. If no output transition occurs

during the watchdog timeout period, the watchdog output

(WDO) pulls low.

±0.5% Reset threshold accuracy at room temperature

±2% Reset threshold accuracy over temperature

extremes

■

Reset assertion down to 1V V_CC

■

28 µA V_CCsupply current

Applications

Embedded Controllers and Processors
