Over-Temperature Protection (OTP)80x嘉泰姆
The over-temperature circuit limits the junction temperature of the CXSD62103. When the junction80x嘉泰姆
UGTAE and LGATE low, allowing the devices to cool.The thermal sensor allows the converters to start a80x嘉泰姆
soft-start process and regulate the output voltage again Junction Temperature (TJ) during continuous thermal80x嘉泰姆
overload conditions, increasing the lifetime of the device.80x嘉泰姆
OVP80x嘉泰姆
The over-voltage protection (OVP) circuit monitors the FB (VFB) voltage to prevent the output from over-voltage.80x嘉泰姆
When the VFB rises to 150% of the EAP voltage (VEAP),the CXSD62103 turns off high-side and turn on low-side80x嘉泰姆
MOSFETs to sink output voltage (VOUT). As soon as theVFB falls below 125% of VEAP, the OVP comparator is80x嘉泰姆
disengaged. The chip will restore its normal operation.80x嘉泰姆
UVP80x嘉泰姆
The under-voltage protection circuit monitors the voltage on FB (VFB) by Under-Voltage (UV) comparator to protect80x嘉泰姆
the PWM converter against short-circuit conditions.When the VFB falls below the falling UVP threshold (50%VEAP), a fault signal is generated and the device turns off high-side and low-side MOSFETs. The converter shuts80x嘉泰姆

down and the output is latched to be floating.80x嘉泰姆
