General Description

The ASM1817 voltage supervisory device with low-power, 3.3V/

3.0V µP Reset, active HIGH, Push-Pull output. Maximum

supply current over temperature is a low 15µA.

The ASM1817 generates an active HIGH reset signal whenever

the monitored supply is out of tolerance. A precision reference

and comparator circuit monitor power supply (V

)

level.

Tolerance level options are 5%, 10% and 20% percent. When

an out-of-tolerance condition is detected, an internal power-fail

signal is generated which forces an active HIGH reset signal.

After V

returns to an in-tolerance condition, the reset signal

remains active for 150ms to allow the power supply and system

microprocessor to stabilize.

Typical Operating Circuit

ASM1817

The ASM1817 is designed with a push-pull output stage and

operates over the extended industrial temperature range.

Devices are available in compact surface mount SOT-23

packages and 3-lead TO-92 packages.

Other low power products in this family include the ASM1810/

11/12/15/16, ASM1233D and ASM1233M.
