Product Summary
The MCP1702T-3302E/MB is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. Both devices are available with a choice of seven different trip voltages and both have open drain outputs. The MCP1702T-3302E/MB has an internal 5 kΩ pullup resistor. Both devices have active low RESET pins. The MCP1702T-3302E/MB will assert the RESET signal whenever the voltage on the V DD pin is below the trip-point voltage.
