FUNCTION
Current-Limit-Type Select Mode.
CLTS_MODE = 0: CLTS1 and CLTS2 are sampled only when (VIN – V_OUT) < 0.6V.
CLTS_MODE = 1: CLTS1 and CLTS2 are continuously sampled.
Current-Limit-Type-Select Logic-High Voltage. Connect CLTS_MODE/CLTS1/CLTS2 to CLHS for
logic-high.
Current-Limit-Type Select 1. See Table 1.
Current-Limit-Type Select 2. See Table 1.
36V Capable Active-Low Enable Input. See Table 2.
Overvoltage Protection Input. Bypass IN to ground with a 0.47µF ceramic capacitor.
Externally Programmable Overvoltage Lockout Threshold. Connect OVLO to GND to use the
default internal OVLO threshold. Connect OVLO to an external resistor-divider to define a
threshold externally and override the preset internal OVLO threshold.
Externally Programmable Undervoltage Lockout Threshold. Connect UVLO to GND to use
the default internal UVLO threshold. Connect UVLO to an external resistor-divider to define a
threshold externally and override the preset internal UVLO threshold.
Overload-Current-Limit Adjust. Connect a resistor from SETI to GND to program the overcurrent
limit. SETI must be connected to a resistor. If SETI is connected to GND, the FETs turn off and
FLAG is asserted. Do not connect more than 10pF to SETI.
