产品信息

The MAX803/NCP803 is a cost-effective system supervisor circuit designed to monitor V
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 V
falling through the reset voltage threshold. Reset is maintained active for a timeout period which trimmed by factor after V
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 V
= 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 V
line. Low supply current of 0.5 µA (V
= 3.3 V) make this device suitable for battery powered applications.

  • Four Guaranteed Minimum RESET Output Duration
  • (1ms, 20ms, 100ms and 140ms)
  • RESET Output Guaranteed to VCC = 1.0 V
  • Low 0.5 uA Supply Current
  • V
  • Transient Immunity
  • Small SOT-23 and SC-70 Package
  • No External Components
  • Wide Operating Temperature: -40°C to 105°C
