Introduction
The MIC809MU-TR is a hot-swap supervisor for an off-line or buck supply with a range input of 16V to 32V, providing brownout protection and features a time-out circuit and reset output. It is designed to provide on/off control with 15V/48mA current capability, suitable for driving relays, power MOSFETs, or other on/off load circuits. The unit can provide real-time monitoring and protection of an off-line or buck supply, providing brownout protection for sensitive circuitry. It also features a time-out circuit and reset output for added protection.

Application fields
The MIC809MU-TR’s low-side drive output and integrated MOSFET stage, especially matched with its wide input voltage range of 16V to 32V is suitable for a variety of applications including industrial and telecommunications equipment, automotive electronics, electronic gaming, and home appliances. It is ideal for use in applications requiring brownout protection such as standby power supplies, data security, boot mechanisms, and HID lighting.

Working principle
The MIC809MU-TR has an internal timer circuit that performs timeouts of 300ms, 2.25ms, and 25ms with adjustable reset voltage thresholds from 7V to 15V. The output is connected to an external MOSFET or Triac for ON/OFF control and the enable pin is ON when high. When the enable pin is asserted high, current flows through the MOSFET or Triac, allowing for output voltage to be present at the load. When the enable pin is asserted low, the output voltage is blocked and current no longer flows to the load, turning the output off. The device also features a thermal shutdown protection circuit that shuts down the device operation when the temperature exceeds the limit set on the package.

Conclusion
The MIC809MU-TR hot-swap supervisor is an ideal solution for off-line or buck supplies requiring brownout protection. Its low-side drive output and integrated MOSFET stage, along with its wide input voltage range of 16V to 32V, makes it a suitable choice for industrial and telecommunications equipment, automotive electronics, electronic gaming, and home appliances. Its time-out circuit with adjustable reset voltage from 7V to 15V, allows it to conform to various application requirements, while its integrated thermal shutdown protection reduces the possibility of damage due to excessive temperature.
