SG6513/T is a controller designed to provide voltage, current and temperature supervision function, remote on/off (PSON) function, power good (PGO) indicator function, and fault protection (FPO) function for switching power systems.
The SG6513/T is a PC power supply supervisor designed to provide voltage, current, and temperature supervision functions along with remote on/off (PSON) control. It monitors 3.3V, 5V, and 12V rails for over-voltage protection (OVP), over-current protection (OCP), under-voltage sense (UVS), and under-voltage protection (UVP). The device also includes an open drain output for the Power Good (PGO) and Fault Protection Output (FPO) pins.
| Supply Voltage Range (VDD) | 4V to 15V |
|---|---|
| Power Good Delay | 300mS |
| Over-voltage Protection Threshold (VS12) | Typ. 13.8V |
| Under-voltage Sense Threshold (VS5) | Typ. 4.2V |
| Operating Temperature Range | -40 to 85 C |
The PSON pin is a logic input for remote On/Off control from the CPU or main-board, with power supply turn-on/off delays of 38mS and 115mS respectively.
For the SG6513T model, an NTC thermistor is connected to the RT pin; when the voltage drops below 0.95V due to high temperature, protection is enabled.
