UTC2000T-I from Microchip Tech, in a QFN-16-EP(3x3). 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 OCS# input Active-low fault input (Schmitt-triggered, internal ~100 µA pull-up). Asserted by the +5V VBUS power-supply device to notify the UTC2000 of a system fault (typically overcurrent/overvoltage). All digital control outputs revert to their default deasserted state while OCS# is asserted, and FAULT_IND latches high until reset/power cycle.
2 CFG_SEL input Analog configuration-select input sampled at power-on (at Vcfg_samp) to place the device in DFP or UFP mode and select the DFP charging profile (Legacy 500 mA / 900 mA, 1.5 A, or 3.0 A). Voltage thresholds are defined in Table 3-1 (DFP) and Table 3-2 (UFP).
3 ENABLE input Active-high controller enable (Schmitt-triggered digital input). When low, the UTC2000 remains in the Disabled Idle state with default deasserted outputs. If unused, tie to VDD through a 10 kΩ pull-up resistor.
4 FAULT_IND output Active-high fault indicator output (O25, 25 mA sink/source push-pull). Asserted after an OCS# overcurrent event or a VMON overvoltage event; cleared by toggling ENABLE (OCS# case) or by a power cycle (VMON case).
5 AUDIO_ADAPTER/CONNECTED# output Muxed function output. In DFP modes: active-high AUDIO_ADAPTER output (O25) indicating detection of a USB audio adapter (used to toggle a high-speed USB/audio switch). In UFP mode: open-drain active-low CONNECTED# output (OD25) that asserts when a valid USB Type-C connection is detected on the CC pin and VBUS is within range.
6 CC2 input USB Type-C CC2 monitor pin (ADC input). Samples the CC2 line voltage to detect connect/disconnect, Rd/Ra pull-downs, plug orientation, and charging capability. Detection thresholds are defined in Table 3-1 (DFP) and Table 3-2 (UFP).
7 CC1 input USB Type-C CC1 monitor pin (ADC input). Samples the CC1 line voltage to detect connect/disconnect, Rd/Ra pull-downs, plug orientation, and charging capability. Detection thresholds are defined in Table 3-1 (DFP) and Table 3-2 (UFP).
8 VCONN2_OUT#/LEGACY_IND# output Muxed open-drain output (OD25, 25 mA). In DFP modes: active-low VCONN2_OUT# controls the external switch supplying 5 V VCONN to CC2 for active-cable circuitry. In UFP mode: active-low LEGACY_IND# asserts when a valid USB Type-C connection is detected with legacy 500 mA / 900 mA charging capability.
9 VCONN1_OUT#/1.5A_IND# output Muxed open-drain output (OD25, 25 mA). In DFP modes: active-low VCONN1_OUT# controls the external switch supplying 5 V VCONN to CC1 for active-cable circuitry. In UFP mode: active-low 1.5A_IND# asserts when a valid USB Type-C connection is detected with 1.5 A charging capability.
10 PPC_EN/3.0A_IND# output Muxed output. In DFP modes: active-high PPC_EN (O25) enables the external 5 V VBUS port-power controller when a valid USB Type-C connection is detected. In UFP mode: active-low 3.0A_IND# (OD25) asserts when a valid USB Type-C connection is detected with 3.0 A charging capability.
11 PLUG_ORIENTATION# output Open-drain active-low plug-orientation indicator output (OD25, 25 mA). Remains high (unasserted) in the default unconnected state or when an Rd pull-down is detected on CC1. Asserts low when an Rd pull-down is detected on CC2, indicating a flipped plug - used to drive the external USB mux/switch.
12 VMON input VBUS voltage-monitor ADC input. Monitors the USB receptacle VBUS (via an external resistor divider). If VMON exceeds 0.8 V (corresponding to >6.4 V on VBUS), the device enters the fault state and deasserts all outputs. Required in UFP modes; in DFP modes, if unused, tie to GND through a 10 kΩ pull-down resistor.
13 VSS power_in Device ground. The exposed pad on the underside of the QFN package must also be connected to VSS/ground.
14 NC unconnected No connect. Leave unconnected (or tie per Microchip recommendation).
15 NC unconnected No connect. Leave unconnected (or tie per Microchip recommendation).
16 VDD power_in 5.0 V power input (operating range 4.5 V to 5.5 V). A minimum of one 0.1 µF bypass capacitor placed close to the pin is recommended. The high level of all digital outputs is referenced to VDD.
17 EP power_in Exposed thermal/ground pad on the underside of the QFN-16 package. Must be connected to VSS/ground for proper operation and thermal performance.
