SGM810 - Microprocessor Supervisory

This page provides the datasheet information for the SGM810, a member of the SGM803 Microprocessor Supervisory family.

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.

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.

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. This holds the microprocessor in a reset state until conditions have stabilized. The RESET output remains operational with VCC as low as 1V. The SGM803 and SGM809 provide an active low reset signal ( RESET ) while the SGM810 provides an active high signal (RESET) output. The SGM809/SGM810 have push-pull outputs, whereas the SGM803 has an open-drain output, which requires an external pull-up resistor.
