MAX803: Very Low Supply Current 3-Pin Micropocessor Reset Monitor
The MAX803/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 µsec of VCC falling through the reset voltage threshold. Reset is maintained active for a timeout period which trimmed by factor after VCC rises above the reset threshold. The MAX803/NCP803 has an open drain active-low RESET(bar) output. The output of the MAX803/NCP803 is guaranteed valid down to VCC = 1.0 V and is available in a SOT-23 and SC-70 package. The MAX803/NCP803 is optimized to reject fast transient glitches on the VCC line. Low supply current of 0.5 µA (VCC = 3.3 V) make this device suitable for battery powered applications.
