... Output voltage pin. This pin is connected to the input through a low R MOSFET switch fault is detected and the STBP120 is not disabled (controlled by the EN input), this switch is turned on and the output voltage follows the input voltage. The output is disconnected from the input when the input voltage is under the UVLO threshold or above the OVLO threshold, when the chip temperature is above the thermal shutdown threshold or when the chip is disabled by the EN input ...

... Enable input (EN) This logical input (active-low) can be used to enable or disable the device. When EN input is driven high, the STBP120 enters the standby mode and the power output is disconnected from the input. When EN input is driven low and all operating conditions are within specified limits, the power output is connected to the input ...

... STBP120 but may be required by the charger IC. 2. The STBP120 MOSFET switch topology allows the current to also flow in the reverse direction, from OUT to IN, which can be useful for powering external peripherals from the system connector. The charger IC should not contain the reverse diode to prevent the battery pack voltage from appearing on the system connector ...

... Operation 3 Operation The STBP120 provides overvoltage protection for positive input voltage using a built-in low R DS(on) 3.1 Power-up At power-up, with EN = low, the MOSFET switch is turned on after delay, t the input voltage exceeds the UVLO threshold to ensure the input voltage is stabilized. After an additional 50 ms delay, t The FLT output state is valid for V 3 ...

... For available OVLO thresholds and hystereses, please see the 3.5 Thermal shutdown If the STBP120 internal junction temperature exceeds the T switch is turned off and the fault indication output FLT is driven low. To improve thermal stability, this circuit has a 20 °C hysteresis, T rises above the threshold level V ...

... It must be ensured that the clearances between PCB tracks satisfy the high voltage design rules. ● Input capacitor, C1, should be located as close as possible to the STBP120 device. It should be a Low-ESR ceramic capacitor. Also the protective resistors R (if used) should be located close to the STBP120. ● ...
