SGM810 - Microprocessor Supervisory

Download the SGM810 datasheet PDF. This datasheet also covers the SGM803 variant, as both devices belong to the same microprocessor supervisory family and are provided as variant models within a single manufacturer datasheet.

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.

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.
