TPS25810RVCR

Texas Instruments · Interface - Specialized · WQFN-20-EP(3x4)

TPS25810RVCR from Texas Instruments, in a WQFN-20-EP(3x4). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 FAULT tri_state Open-drain logic output that asserts low to indicate current limit or thermal shutdown event due to over temperature.
2 IN1 power_in VBUS input supply (4.5-6.5 V); internal power switch connects IN1 to OUT.
3 IN1 power_in VBUS input supply (4.5-6.5 V); internal power switch connects IN1 to OUT.
4 IN2 power_in VCONN input supply (4.5-5.5 V); internal power switch connects IN2 to CC1 or CC2 based on cable polarity.
5 AUX power_in Auxiliary input supply (2.9-5.5 V); connect to always-alive system rail for Power Wake feature operation.
6 EN input Enable logic input (0-5.5 V) to turn device on and off with rising threshold 1.15 V and falling threshold 0.875 V.
7 CHG input Charge logic input (0-5.5 V) to select between standard USB (500-900 mA) or Type-C current sourcing capability.
8 CHG_HI input High-charge logic input (0-5.5 V) to select between 1.5-A and 3-A Type-C current sourcing capability when CHG is set to Type-C mode.
9 REF_RTN passive Precision signal reference return (internally connected to GND); connect to REF pin via 100-kΩ, 1% tolerance resistor.
10 REF input Analog input (output voltage 0.78-0.82 V typical) used to generate internal current reference; requires 100-kΩ, 1% tolerance resistor to REF_RTN.
11 CC1 bidirectional Analog input/output (0-2.45 V) that connects to USB Type-C receptacle CC1 pin for detecting attachment, cable orientation, and accessory modes.
12 GND power_in Power ground for device supply return and package reference.
13 CC2 bidirectional Analog input/output (0-2.45 V) that connects to USB Type-C receptacle CC2 pin for detecting attachment, cable orientation, and accessory modes.
14 OUT power_out Power switch output (5 A maximum continuous, 3.4 A limit in 3-A mode with 34-55 mΩ on-resistance) providing VBUS to Type-C connector.
15 OUT power_out Power switch output (5 A maximum continuous, 3.4 A limit in 3-A mode with 34-55 mΩ on-resistance) providing VBUS to Type-C connector.
16 DEBUG tri_state Open-drain logic output that asserts low (max 250 mV at 1 mA) when Type-C Debug Accessory (both CC pins at Rd) is detected.
17 AUDIO tri_state Open-drain logic output that asserts low (max 250 mV at 1 mA) when Type-C Audio Adapter Accessory (both CC pins at Ra) is detected.
18 POL tri_state Polarity open-drain output that asserts low (max 250 mV at 1 mA) when CC2 detects Rd, indicating reversed cable orientation and providing super-speed line mux control.
19 UFP tri_state Open-drain logic output that asserts low (max 250 mV at 1 mA) when Type-C Upstream Facing Port (UFP) device is detected on either CC line.
20 LD_DET tri_state Load-detect open-drain output that asserts low (max 350 mV at 1 mA) when 3-A source detects load current exceeding 1.95-A nominal threshold for multi-port power management.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
