1 / 10 page © Semiconductor Components Industries, LLC, 2013 June, 2013 − Rev. 7 1 Publication Order Number: MAX803/D MAX803 Series, NCP803 Series Very Low Supply Current 3-Pin Microprocessor 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 msec of VCC falling through the reset voltage threshold. Reset is maintained active for a timeout period which is trimmed by the factory after VCC rises above the reset threshold. The MAX803/NCP803 has an open drain active−low RESET output. Both devices are available in SOT−23 and SC−70 packages. The MAX803/NCP803 is optimized to reject fast transient glitches on the VCC line. Low supply current of 0.5 mA (VCC = 3.2 V) make these devices suitable for battery powered applications. Features • Precision VCC Monitor for 1.5 V, 2.5 V, 3.0 V, 3.3 V, and 5.0 V Supplies • Precision Monitoring Voltages from 1.2 V to 4.9 V Available in 100 mV Steps • Four Guaranteed Minimum Power−On Reset Pulse Width Available (1 ms, 20 ms, 100 ms, and 140 ms) • RESET Output Guaranteed to VCC = 1.0 V • Low Supply Current • VCC Transient Immunity • No External Components • Wide Operating Temperature: −40°C to 105°C • These Devices are Pb−Free and are RoHS Compliant Typical Applications • Computers • Embedded Systems • Battery Powered Equipment • Critical Microprocessor Power Supply Monitoring VCC VCC VCC RESET RESET MAX803 NCP803 GND GND Figure 1.
