Working Principles

The TPS3852H33QDRBRQ1 is a voltage supervisor IC that monitors the system voltage and generates a reset signal when it falls below a specified threshold voltage. It operates by comparing the system voltage with an internal reference voltage. When the system voltage drops below the threshold, the reset signal is asserted, indicating a power failure or an out-of-specification condition. The manual reset input allows external control over the reset function. The open-drain RESET output can be connected to other devices for system-level coordination.
