TPS3514 描述
The TPS3514 is a PC switching power-supplysystem monitor with minimum external components. It provides under-voltage lockout (UVLO), over-voltage (OV), under-voltage (UV), over-current (OC) protection circuits, power-good indicator, and on/off control.
UVLO thresholds are 4.45V (on) and 3.65V (off). Over-current protection (OCP) and over-voltage protection (OVP) monitor 3.3V, 5V, and 12V supplies. When an OC or OV condition is detected, the power-good output (PGO) is asserted low and the fault protection output (FPO) is latched high. PSON from low-to-high resets the latch. The OCP function will be enabled 75ms after PSON goes LOW with PGI HIGH and a debounce of typically 38ms. A built-in 2.3ms delay with 38ms debounce from PSON to FPO output is enabled at turn-off.
