Description

The HY510N is PC Power Supply Supervisor. A PC power supply supervisor, also known as a power supply supervisor IC or PSU supervisor, is an integrated circuit (IC) or semiconductor device designed to monitor and control the power supply unit (PSU) in a personal computer or other electronic devices. These supervisors play a crucial role in ensuring the proper operation, safety, and reliability of the power supply and the overall system.

The device provides protection circuits, power good output (PGO), fault protection latch (FPL_N), and a protection detector function (PDON_N) control. It can minimize external components of switching power supply systems in personal computer. The Over Voltage Detector (OVD) monitors 3.3V, 5V, 12V input voltage level. The Under Voltage Detector (UVD) monitors 3.3V, 5V input voltage level. When OVD or UVD detect the fault voltage level, the FPL_N is latched HIGH and PGO go low. The latch can be reset by PDON_N goo HIGH.

(1) Voltage Monitoring: These ICs monitor the output voltages of the power supply, such as +12V, +5V, +3.3V, and others. They compare the monitored voltages with predefined thresholds and provide feedback to the control circuitry for voltage regulation.

(2) Overvoltage and Undervoltage Protection: The PWM supervisor IC incorporates protection circuitry to detect overvoltage and undervoltage conditions. When these conditions occur, the IC triggers appropriate actions, such as shutting down the power supply or activating protective measures to prevent damage to the system.

(3) Overcurrent Protection: These ICs monitor the current flowing through the power supply’s output circuits. If the current exceeds a predefined limit, the PWM supervisor IC can initiate protective measures, such as reducing the duty cycle of the PWM signal or shutting down the power supply.
