SGM809 Microprocessor Supervisory

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 res.

SGM809 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. FEATURES

* Precision Voltage
