LM3710/LM3711

Microprocessor Supervisory Circuits with Power Fail

Input, Low Line Output, Manual Reset and Watchdog

Timer

General Description

Features

n Standard Reset Threshold voltage: 3.08V

n Custom Reset Threshold voltages: For other voltages

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

National Semiconductor Corp.

The LM3710/LM3711 series of microprocessor supervisory

circuits provide the maximum flexibility for monitoring power

supplies and battery controlled functions in systems without

backup batteries. The LM3710/LM3711 series are available

in MSOP-10 and 9-bump micro SMD packages.

n No external components required

Built-in features include the following:

n Manual-Reset input

n RESET (LM3710) or RESET (LM3711) outputs

n Precision supply voltage monitor

n Factory programmable Reset and Watchdog Timeout

Delays

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

brownout conditions. RESET is guaranteed down to V_CCof

1.0V.

Manual Reset Input: An input that asserts reset when pulled

low.

n Separate Power Fail comparator

n Available in micro SMD package for minimum footprint

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

warning, or to monitor a power supply other than V_CC

0.5% Reset threshold accuracy at room temperature

2% Reset threshold accuracy over temperature

extremes

Low Line Output: This early power failure warning indicator

goes low when the supply voltage drops to a value which is

2% higher than the reset threshold voltage.

n Reset assertion down to 1V V_CC(RESET option only)

n 28 µA V_CCsupply current

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, reset is activated.

Applications

n Embedded Controllers and Processors

n Intelligent Instruments

n Automotive Systems

n Critical µP Power Monitoring
