IC ground reference
Chip bias, Controlled Voltage Input, Undervoltage Lock Out (UVLO). VIN provides chip
bias voltage. At VIN < 1.7V chip functionality is disabled, FLT is active and floating and
OUT is held low. Range 0V to 5.5V
Enable/Disable inputs, Active high (EN) and active low (EN) options enable the power
switch. These inputs have internal 1MΩ pull off resistors. Range 0V to VIN
Overcurrent Fault Indicator. Overcurrent fault indicator. FLT floats and is disabled until
VIN >V
expired. Fault is not signaled due to over-temperature shut down. Range 0V to VIN
Controlled Supply Output. Upon an OC condition I
response time is within 200µs. This output will remain in current limit for a nominal
12ms before being turned off either for the latch or auto retry versions. Range 0V to VIN
This pin is not electrically connected internally
