The voltage supervisors extensive family of parts includes voltage supply monitors, trackers, margining controllers, sequencers, push button controllers,  and the new power monitors.  All of these devices improve DC/DC converter functionality and feature a high degree of accuracy, integration and configurability, resulting in more cost efficient designs that would otherwise be burdened with multiple complicated components when designed the "traditional way".  This family strives to provide convenient all-in-one solutions for many of today's growing number of digital power management applications.

The Microchip Technology Inc. MCP120/130 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 MCP130 has an internal 5 kΩ pullup resistor. Both devices have active low RESET pins. The MCP120/130 will assert the RESET signal whenever the voltage on the VDD pin is below the trip-point voltage.
