PS238
Overview
PS238 is specially designed for switching power supply system. Four important functions of PS238 are the followings: over-voltage protection, over-current protection, under-voltage protection and power good signal generating.
- Over/Under-voltage protection and lock out Over-current protection and lock out Additional protection input Fault protection output with open drain output stage Open drain power good output signal for power good input Built-in 300mS power good delay AC on 75ms delay for UV/OC protection 38mS PSON/ control de-bounce Wide power supply range (4.2V~16V) Special care for AC power off 8-Channel Seccondary Monitoring IC -1- Version：A.001 PS238 Block Diagram VS delay 155KΩ 17uS UV Vref 9KΩ Vref 16KΩ OV 38mS De-bounce H: 4mS
