NCP803 Very Low Supply Current 3-Pin Microprocessor Reset Monitor
The NCP803 is a cost-effective system supervisor circuit designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required. The reset output is driven active within 10 ตsec of VCC falling through the reset voltage threshold. Reset is maintained active for a minimum of 140 msec after VCC rises above the reset threshold. The NCP803 has an open drain active-low RESET output. The output of the NCP803 is guaranteed valid down to VCC = 1.0 V and is available in a SOT-23 package. The NCP803 is optimized to reject fast transient glitches on the VCC line. Low supply current of 1.0 ตA (VCC = 3.2 V) make this device suitable for battery powered applications.
