Figure 24. Over-Voltage Protection Mechanism

Under-Voltage Protection

When the output voltage is lower than VID-650mV with

µs filter time, UVP is triggered and all PWMs are in

tri-state to turn off high-side and low-side power

MOSFETs. UVP is masked during DVID period and

µs after VID settles. The mechanism is illustrated in

Figure 25.

All protections are reset only by VCC/VRON toggle.

UVP and OCP protections are listed in Table 18. Note

that the real filter time also depends on the magnitude

of detected signal. The signal magnitude affects analog

comparator’s overdrive voltage and output slew rate.

The RT3624LE provides protection flag to promptly

determine which kind of protections is triggered. As

protection happens, VREF is forced to be 1V/1.5V/2V

for OVP/UVP/SUM_OCP, respectively.
