描述 Description

The AWS70708 microprocessor supervisory circuit reduces the complexity and number of components required to monitor power supply and monitor microprocessor activity. It significantly improves system reliability and accuracy compared to separate ICs in discrete components.The AWS70708 provides power supply monitoring circuitry that generates a reset output during power-up, power-down and brownout conditions. The reset output remains operational with VCC as low as 1V.In addition, there is a 1.25V threshold detector for power-fail warning, low-battery detection, in monitoring an additional power supply. An active-low manual-reset input (MRB) is also included.The AWS70708 available in Green WBSOP-8L package. It operates over an ambient temperature range of -40°C to +85°C.
