SGM803 Datasheet Microprocessor Supervisory

Manufacturer: SG Micro

Overview: SGM803/SGM809/SGM810 Microprocessor Supervisory Circuit in 3-Pin SOT-23.

General Description

The SGM803/SGM809/SGM810 supervisory circuits monitor the power supply voltage in microprocessor and digital systems.

They provide a reset output during power-up, power-down and brownout conditions.

On power-up, an internal timer holds reset asserted for 240ms.

Key Features

  • built-in glitch immunity, making it immune to fast transients on VCC. The low supply current of typically 13μA makes the SGM803/SGM809/SGM810 ideal for use in portable, battery operated equipment. All are specified over the extended -40℃ to +125℃ temperature range.
