Pin Function
Switch Enable Input: Gate control pin of the output MOSFET available as an
active high (–1) or active low (–2) input signal.
Fault Status Output: Open drain N-Channel device, active low. This pin
indicates an overcurrent, or thermal shutdown condition. For an overcurrent
event, /FAULT is asserted if the duration of the overcurrent condition lasts
longer than 28ms.
Ground Connection: Tie to analog ground.
Current Limit Set: A resistor, R
limit threshold as CLF/R
the electrical characteristics table. For the MIC2040/41, the continuous
output current range is 0.25A to 1.5A.
Switch Input Supply: The drain of the output MOSFET. The range of input
for the switch is 0.8V to 5.5V. These pins must be externally connected
together.
Switch Output: The source of the output MOSFET. These pins must be
externally connected together.
Bias Supply Input: This input pin supplies bias to operate the switch with
range from 1.6V to 5.5V. When switching voltage (V
5.5V and the use of a single supply is desired, connect VBIAS to VIN
externally.
Undervoltage Lockout Adjust Input: With this pin left open, the UVLO
threshold is internally set to 1.45V. When the switching voltage (V
below 1.6V, connecting an external resistive divider to this input will lower
the UVLO threshold. The total resistance must be less than 200kΩ. See
“Applications Information” for further detail.
