Power supply supervisor circuits are typically found in power systems, providing power supply monitoring and supervision. The S-80932CLPF-G62TFG is a Multi-Voltage Power Supply Supervisor which monitors multiple outputs of power supplies and provides an active-low reset signal to the CPU or other peripheral devices. This product is very useful for systems that need to monitor power and detect faults quickly and accurately.

The S-80932CLPF-G62TFG is designed to ensure robust power-on sequencing, thermal protection, and overvoltage/undervoltage detection. It features a single-ended output voltage supervisor, which supervises the negative DC voltage rail. This voltage supervisor has a selectable voltage trip point between 0 to -4.2 V, which is set using an on-chip register. Additionally, the device has an over-current monitor for preventing the occurrence of restarts, and a temperature monitor for shutting down the systems during extreme temperature conditions.

This Multi-Voltage Power Supply Supervisor is ideal for embedded systems, and is well suited for power systems that need reliable power supplies and must survive even in harsh environments.

The working principle of the S-80932CLPF-G62TFG Supervisor is based on the comparison of two separate reference voltages. First, a voltage supervisor reference voltage, V_SR, is generated on-chip and is compared with the selected voltage of the negative DC voltage rail, V- (V\_Neg). When the voltage on V- is higher than the reference voltage, then the reset signal is asserted low, otherwise, it is maintained high.

The S-80932CLPF-G62TFG also contains an internal over-current monitoring circuit, which is designed to monitor the current consumption of the systems it is attached to. The over-current monitor will assert the reset signal to a low level when the current consumption exceeds the set threshold, preventing system restarts or outages in the event of over-current conditions.

The S-80932CLPF-G62TFG further incorporates an on-chip temperature monitor, which is designed to shut down the systems if the internal temperature of the IC exceeds the threshold limit. This feature helps ensure that the device will be able to operate correctly even in extreme temperature conditions. Additionally, this product features an enable pin, which can be used to enable/disable the reset output.

The S-80932CLPF-G62TFG Multi-Voltage Power Supply Supervisor is a useful and reliable product for embedded systems that need reliable and robust power supplies, and must survive in harsh environments. It features a voltage supervisor, over-current monitoring, and temperature monitoring. The voltage supervisor and current monitor provide fast, accurate fault detection for most power systems and help prevent restarts or outages. The temperature monitor provides protection from extreme temperature conditions, ensuring the system will continue to operate correctly even in the most severe environments.
