5.7 Under Voltage Lockout Protection Circuit Block (UVLO)
The circuit protects against IC malfunction and system destruction/deterioration in a transitional state or a momentary drop of when
the internal reference voltage starts. It detects a voltage drop at the VIN1 pin and stops IC operation. When voltages at the VIN1 pin
exceed the threshold voltage of the under voltage lockout protection circuit, the system is restored.
5.8 Over Temperature Protection Block (OTP)
The circuit protects an IC from heat-destruction. If the junction temperature reaches 135°C, the circuit turns off the CH1 and CH2
operation, When the junction temperature comes down to + 110°C, the CH1 and CH2 are returned to the normal operation.
