Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Power input that connects to the DRAIN of the internal FET; this is the same IN net as pin 2. |
| 2 | IN | power_in | Power input that connects to the DRAIN of the internal FET. |
| 3 | B_GATE | output | Blocking FET gate driver output; connect to the GATE of the external NFET, and leave floating if no external FET is used. |
| 4 | DRV | output | Blocking FET fast pulldown switch drive; connect to the GATE of the external pulldown switch, and leave floating if no external N-FET is used. |
| 5 | IN_SYS | power_in | Power input and supply voltage of the device; connect to the source of the blocking FET when one is used, or short to IN when it is not. |
| 6 | UVLO | input | Input for setting the programmable undervoltage lockout threshold; an undervoltage event turns off the internal FET and asserts FLT, and connecting to GND selects the internal default threshold. |
| 7 | PLIM | input | Output power limit threshold input for TPS26633; connect a resistor from PLIM to GND to set the output power limit, or connect PLIM to GND if the feature is not used. |
| 8 | GND | power_in | Connect to system ground. |
| 9 | dVdT | bidirectional | A capacitor from this pin to GND sets the output voltage slew rate. |
| 10 | ILIM | bidirectional | A resistor from this pin to GND sets the overload and short-circuit current limit. |
| 11 | MODE | input | Mode selection pin for overload fault response. |
| 12 | SHDN | input | Shutdown pin; pulling SHDN low puts the device into low-power shutdown mode, and cycling SHDN resets the device after a latched fault. |
| 13 | IMON | output | Analog current monitor output that sources a scaled-down ratio of the FET current through a resistor to GND; leave floating if unused. |
| 14 | FLT | output | Open-drain fault event indicator output; leave floating or connect to GND if unused. |
| 15 | PGTH | input | PGOOD comparator input. |
| 16 | PGOOD | output | Active-high power-good output that goes high when PGTH crosses V(PGTHR) and the internal FET is enhanced, and goes low when V(PGTH) hits V(PGTHF); connect to GND or leave floating if unused. |
| 17 | OUT | power_out | Power output of the device. |
| 18 | OUT | power_out | Power output of the device. |
| 19 | N.C | unconnected | No connect. |
| 20 | N.C | unconnected | No connect. |
| 21 | N.C | unconnected | No connect. |
| 22 | N.C | unconnected | No connect. |
| 23 | N.C | unconnected | No connect. |
| 24 | N.C | unconnected | No connect. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
