UIC813中文资料3-PIN MICROPROCESSOR  RESET CIRCUITS数据手册UTC规格书

描述 Description

The UTC UIC813 series are resetting circuits which can monitor power supplies especially in microprocessor based systems. In normal operation, the UTC UIC813 series can assert a reset under any of the following situation: the power supply drops below a designated reset threshold level (which is available for 3V or 3.3Vor 5V system). There is an internal active high RESET output which has already been guaranteed to remain asserted for at 140ms least while V CC  rises above the designed threshold level.

特性 Features

Voltage monitor for 3V or 3.3V or 5V power suppliesValid RESET remains with V CC  as low as 1VTypical supply current: 10μAFixed 140ms minimum reset pulse width Push-Pull Reset Active High Output.
