TPS26601RHFR 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 internal connection; leave floating per datasheet. |
| 2 | N.C | unconnected | No internal connection; leave floating per datasheet. |
| 3 | N.C | unconnected | No internal connection; leave floating per datasheet. |
| 4 | N.C | unconnected | No internal connection; leave floating per datasheet. |
| 5 | N.C | unconnected | No internal connection; leave floating per datasheet. |
| 6 | N.C | unconnected | No internal connection; leave floating per datasheet. |
| 7 | N.C | unconnected | No internal connection; leave floating per datasheet. |
| 8 | IN | power_in | Power supply input and device supply voltage; operating range 4.2 V to 60 V (absolute max -60 V / 62 V); both IN pins must be connected together to the power source. |
| 9 | IN | power_in | Power supply input and device supply voltage; operating range 4.2 V to 60 V (absolute max -60 V / 62 V); both IN pins must be connected together to the power source. |
| 10 | UVLO | input | Programmable undervoltage lockout comparator input; rising threshold V(UVLOR) = 1.19 V (typ); connect to RTN for factory-set 14.9 V (typ) internal UVLO threshold; leakage current ±100 nA max; must not be left floating. |
| 11 | N.C | unconnected | No internal connection; leave floating per datasheet. |
| 12 | OVP | input | Programmable overvoltage cut-off threshold input (TPS26601); rising threshold V(OVPR) = 1.19 V (typ); connect to RTN for factory-set 32.6 V (typ) internal OVP threshold; maximum external OVP setting is 55 V; input range 0 V to 4 V. |
| 13 | MODE | input | Overload fault-response mode selection input; open = circuit breaker with latch (TPS26601); shorted to RTN = active current limiting with auto-retry; 402 kΩ to RTN = active current limiting with latch-off. |
| 14 | SHDN | input | Active-low shutdown input; pulling below V(SHUTF) = 0.76 V (typ) enters low-power shutdown mode (IQ = 20 µA typ) and resets a latched fault; pull-down must sink ≥ 10 µA at 400 mV to assert; SHDN internal pull-up voltage = 2.7 V (typ). |
| 15 | RTN | power_in | Reference ground for all internal control circuits; all support components (R(ILIM), C(dVdT), R(IMON), UVLO/OVP resistors) must reference to this pin; must NOT be connected directly to GND, as doing so permanently disables reverse polarity protection. |
| 16 | N.C | unconnected | No internal connection; leave floating per datasheet. |
| 17 | GND | power_in | Device signal ground; must be connected to system ground; an internal reverse polarity protection block exists between RTN and GND. |
| 18 | IMON | output | Analog current monitor output; sources a current proportional to load current with GAIN(IMON) = 78.28 µA/A (typ), ±8.5% accuracy; a resistor from this pin to RTN converts current to voltage; leave floating if unused; do not add a bypass capacitor. |
| 19 | ILIM | bidirectional | Current limit programming I/O; a resistor from this pin to RTN sets overload current limit I(OL) = 12/R(ILIM,kΩ) A; internal ILIM bias voltage = 1 V; R(ILIM) range 5.36 kΩ to 120 kΩ programs 0.1 A to 2.23 A (±5% at 1 A). |
| 20 | dVdT | bidirectional | Output voltage ramp rate control I/O; a capacitor from this pin to RTN programs the output voltage slew rate; internal charging current I(dVdT) = 4.7 µA (typ), discharging resistance 14 Ω (typ); leave floating for internal 23.9 V/1.6 ms slew rate. |
| 21 | N.C | unconnected | No internal connection; leave floating per datasheet. |
| 22 | FLT | output | Active-low open-drain fault indicator; asserts during undervoltage, overvoltage, overcurrent, reverse current, thermal shutdown, and startup gate-ramp conditions; pull-down R(FLT) = 85 Ω (typ) at 5 mA; FLT leakage ±200 nA max; leave floating if unused. |
| 23 | OUT | power_out | Power output of the device; IN-to-OUT RON = 150 mΩ (typ) at TJ = 25°C (250 mΩ max over -40°C to +125°C); both OUT pins must be connected together to the load. |
| 24 | OUT | power_out | Power output of the device; IN-to-OUT RON = 150 mΩ (typ) at TJ = 25°C (250 mΩ max over -40°C to +125°C); both OUT pins must be connected together to the load. |
| 25 | PowerPad | power_in | Exposed thermal pad; must be soldered to the RTN plane on the PCB using multiple vias for enhanced thermal performance; do not use as the only electrical connection to RTN. |
