Input Voltage Protection in Charge Mode
Input Over-Voltage Protection (VBUSOVPI)
The TPS65200 provides a built-in input over-voltage protection to protect the device and other components
against damage if the input voltage (voltage from VBUS to PGND) gets too high. When an input over-voltage
condition is detected, the TPS65200 turns off the PWM converter, sets the VBUSOVPI bit in the INT1 register
and issues an interrupt. Once VVBUS drops below the input over-voltage exit threshold, the fault is cleared and
charge process resumes.
Reverse Current Protection (CHRVPI)
The TPS65200 charger enters HiZ state if the voltage on VBUS pin falls below VCSOUT + VREV, and VBUS is still
higher than the poor source detection threshold, VIN(MIN). The CHRVPI bit is set in the INT2 register and an
interrupt is issued. This feature prevents draining the battery during the absence of VBUS. In HiZ mode, both the
reverse blocking switch Q1 and PWM are turned off.
