TPS26600RHFR from Texas Instruments, in a VQFN-24(5x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | N.C. | unconnected | No connect - unconnected pin |
| 2 | N.C. | unconnected | No connect - unconnected pin |
| 3 | N.C. | unconnected | No connect - unconnected pin |
| 4 | N.C. | unconnected | No connect - unconnected pin |
| 5 | N.C. | unconnected | No connect - unconnected pin |
| 6 | N.C. | unconnected | No connect - unconnected pin |
| 7 | N.C. | unconnected | No connect - unconnected pin |
| 8 | IN | power_in | Power input supply voltage; operating input range 4.2 V to 60 V with absolute maximum ±60 V rating for reverse polarity protection. |
| 9 | IN | power_in | Power input supply voltage; operating input range 4.2 V to 60 V with absolute maximum ±60 V rating for reverse polarity protection. |
| 10 | UVLO | input | Undervoltage lockout threshold input; connect to RTN for 15 V rising factory default or use external resistor divider to program custom threshold between 0 and 60 V. |
| 11 | N.C. | unconnected | No connect - unconnected pin |
| 12 | OVP | input | Overvoltage protection threshold input; connect to RTN for 33 V (TPS26600/1) or 38 V clamp (TPS26602) factory defaults, or use external resistor divider to program threshold. |
| 13 | MODE | input | Mode selection pin for overload fault response; leave open for circuit breaker with auto-retry, pull to RTN with 402 kΩ resistor for current limit with latch-off. |
| 14 | SHDN | input | Shutdown control input; pull below 0.76 V to enter low-power shutdown mode (quiescent current 20 µA typical) or pull above 1 V to enable normal operation. |
| 15 | RTN | passive | Device reference ground for internal control circuits; must remain separate from GND to maintain reverse input polarity protection functionality. |
| 16 | N.C. | unconnected | No connect - unconnected pin |
| 17 | GND | power_in | System ground connection for integrated reverse polarity protection circuit and external component reference. |
| 18 | IMON | output | Analog current monitor output; open-drain sources current proportional to load current (78.4 µA/A typical); connect resistor to RTN to convert to voltage. |
| 19 | ILIM | bidirectional | Current limit threshold control; connect 5.36 kΩ to 120 kΩ resistor to RTN to program overload current limit from 85 mA to 2.35 A with ±5% accuracy at 1 A. |
| 20 | dVdT | bidirectional | Output voltage slew rate control; connect 10 nF to 47 nF capacitor to RTN to program ramp time slower than 1.6 ms default, or leave floating for 1.6 ms ramp. |
| 21 | N.C. | unconnected | No connect - unconnected pin |
| 22 | FLT | output | Fault event indicator open-drain output (active low); asserts during undervoltage, overvoltage, overcurrent, reverse current, or thermal shutdown faults; leave floating if unused. |
| 23 | OUT | power_out | Power output to load with 0 V to 60 V output range; integrated FET path total ON resistance 150 mΩ typical with reverse current blocking. |
| 24 | OUT | power_out | Power output to load with 0 V to 60 V output range; integrated FET path total ON resistance 150 mΩ typical with reverse current blocking. |
