Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Overvoltage-protection input; voltage range −40V to +40V; bypass to GND with 1μF low-ESR ceramic capacitor; ESD rated ±15kV (HBM). |
| 2 | IN | power_in | Overvoltage-protection input; voltage range −40V to +40V; bypass to GND with 1μF low-ESR ceramic capacitor; ESD rated ±15kV (HBM). |
| 3 | IN | power_in | Overvoltage-protection input; voltage range −40V to +40V; bypass to GND with 1μF low-ESR ceramic capacitor; ESD rated ±15kV (HBM). |
| 4 | UVLO | input | Externally programmable undervoltage-lockout threshold; voltage range −0.3V to +6.0V; connect to GND for 19.2V (typ) internal threshold or external divider for 4.5V to 24V adjustment range. |
| 5 | OVLO | input | Externally programmable overvoltage-lockout threshold; voltage range −0.3V to +6.0V; connect to GND for 33V (typ) internal threshold or external divider for 6V to 36V adjustment range. |
| 6 | SETI | input | Current-limit adjustment input; voltage range −0.3V to Min(VIN, 1.22V) + 0.3V; connect resistor to GND to program overcurrent limit between 0.7A and 4.2A; do not connect more than 10pF capacitance. |
| 7 | GND | power_in | Ground reference connection. |
| 8 | HVEN | input | High-voltage-capable active-low enable input; voltage range −40V to +40V; threshold 1V to 3.5V; drive low for normal operation, high to disable; overvoltage protection to 36V. |
| 9 | RIEN | input | Reverse-current enable input; voltage range −0.3V to +6.0V; connect to GND to disable reverse-current protection or to logic-high to activate protection. |
| 10 | EN | input | Active-high enable input; voltage range −0.3V to +6.0V; logic levels 0.4V (low) to 1.4V (high); drive high for normal operation, low to disable. |
| 11 | FLAG | output | Open-drain fault indicator output; voltage range −0.3V to +6.0V; pulls low when overcurrent blanking time (20.7ms typ) exceeds, reverse current detected, thermal shutdown active, OVLO threshold reached, or SETI connected to GND. |
| 12 | OUT | power_out | Power output; voltage range −0.3V to +40V; output of internal FETs; bypass to GND with 1μF ceramic capacitor placed close to device. |
| 13 | OUT | power_out | Power output; voltage range −0.3V to +40V; output of internal FETs; bypass to GND with 1μF ceramic capacitor placed close to device. |
| 14 | OUT | power_out | Power output; voltage range −0.3V to +40V; output of internal FETs; bypass to GND with 1μF ceramic capacitor placed close to device. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
