Under Voltage Lockout (UVLO)

To avoid mis-operation of the device at low input voltages an under voltage lockout is

included that disables the device, if the input voltage falls below 6.0 V.

Current Limit Protection

The Current limit is set by outside resistance (RSENSE), When the SENSE1-SENSE2

voltage larger than 140mV, the current limit is happened that driver can be turned off until

the drop is small than 110mV. The current limit set according to the following equation:
