Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | N.C | unconnected | No connect pin. |
| 2 | N.C | unconnected | No connect pin. |
| 3 | N.C | unconnected | No connect pin. |
| 4 | N.C | unconnected | No connect pin. |
| 5 | N.C | unconnected | No connect pin. |
| 6 | N.C | unconnected | No connect pin. |
| 7 | N.C | unconnected | No connect pin. |
| 8 | IN | power_in | Power input and supply voltage of the device; all IN pins must be connected together and to the power source, with a recommended operating input range of 4.2 V to 60 V. |
| 9 | IN | power_in | Power input and supply voltage of the device; all IN pins must be connected together and to the power source, with a recommended operating input range of 4.2 V to 60 V. |
| 10 | UVLO | input | Input for setting the programmable undervoltage lockout threshold; an undervoltage event turns off the internal FET and asserts FLT, and connecting it to RTN selects the internal default threshold. |
| 11 | N.C | unconnected | No connect pin. |
| 12 | OVP | input | Input for setting the programmable overvoltage protection threshold (TPS26600/1 only); an overvoltage event turns off the internal FET and asserts FLT, and connecting it to RTN selects the internal default threshold (or the overvoltage clamp response on TPS26602). |
| 13 | MODE | input | Mode selection pin for overload fault response, selecting circuit breaker mode when open, active current limiting with auto-retry when shorted to RTN, or active current limiting with latch-off through a 402 kΩ resistor to RTN. |
| 14 | SHDN | input | Shutdown pin; pulling it below 0.76 V enters low-power shutdown mode, and cycling it resets a device latched off by a fault. |
| 15 | RTN | passive | Reference for the device internal control circuits; RTN must not be connected to GND, as this disables reverse input polarity protection and permanently damages the device. |
| 16 | N.C | unconnected | No connect pin. |
| 17 | GND | power_in | Connect GND to system ground. |
| 18 | IMON | output | Analog current monitor output that sources a scaled-down ratio of the FET current; a resistor from this pin to RTN converts it to voltage, and it may be left floating if unused. |
| 19 | ILIM | bidirectional | A resistor from this pin to RTN sets the overload and short-circuit current limit (R(ILIM) range 5.36 kΩ to 120 kΩ). |
| 20 | dVdT | bidirectional | A capacitor from this pin to RTN sets the output voltage slew rate at start-up (10 nF maximum listed in recommended conditions), and leaving it floating gives the internal 23.9 V/1.6 ms ramp. |
| 21 | N.C | unconnected | No connect pin. |
| 22 | FLT | output | Open-drain fault event indicator that is asserted on fault conditions; leave floating if unused. |
| 23 | OUT | power_out | Power output of the device; all OUT pins must be connected together and to the load. |
| 24 | OUT | power_out | Power output of the device; all OUT pins must be connected together and to the load. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
