Product details
Overview
UTC2000-I/MG from Microchip Technology is a USB Type-C™ controller IC designed for Downstream Facing Port (DFP) and Upstream Facing Port (UFP) applications in USB 2.0/3.0 systems. It performs CC1/CC2 analog monitoring, plug orientation detection, VCONN control, audio adapter identification, and VBUS overvoltage monitoring with 4.5V–5.5V operation. Used in laptops, monitors, and USB wall chargers to enable reversible cable support and multi-profile charging.
For engineers reviewing the UTC2000-I/MG datasheet, UTC2000-I/MG pinout, UTC2000-I/MG application, or UTC2000-I/MG equivalent, key selection criteria include DFP/UFP mode configurability via CFG_SEL, open-drain indicator outputs (FAULT_IND, PLUG_ORIENTATION#, CONNECTED#), VBUS voltage monitoring threshold (0.8V on VMON = >6.4V VBUS), and 16-pin QFN package compatibility with USB Type-C receptacle layouts.
Technical Context
The UTC2000-I/MG implements dual-mode USB Type-C port control using two ADC inputs (CC1, CC2) to detect Rd/Ra resistor configurations and determine connection state, orientation, and charging capability. Its internal state machine supports six DFP connection states (e.g., unflipped/flipped passive/active cables, audio adapter) and seven UFP states (legacy/1.5A/3.0A, flipped/unflipped).
Configuration is determined at power-on by CFG_SEL voltage level: 0.0–0.3V (Legacy DFP), 0.7–0.8V (1.5A DFP), 1.2–1.3V (3.0A DFP), or 1.75V–VDD (UFP). Mode switching between DFP profiles is dynamic; UFP↔DFP transition requires power cycle. VMON monitors VBUS via 0.8V threshold (equivalent to 6.4V), triggering fault state and FAULT_IND assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5V to 5.5V - powers all internal circuitry and sets digital output high-level voltage. |
| Operating Temperature | −40°C to +125°C - supports automotive extended temperature requirements without derating. |
| VBUS Overvoltage Threshold | 0.8V on VMON pin (= >6.4V on VBUS) - triggers fault state and deasserts all control outputs. |
| CC Pin Interface | ADC-monitored CC1/CC2 - detects Rd (UFP), Rp (DFP), Ra (active cable), and short-to-ground (audio adapter). |
| Charging Profiles | Legacy (500mA/900mA), 1.5A, and 3.0A DFP modes - selected by CFG_SEL voltage at power-on or runtime (DFP only). |
| Output Drive Capability | O25/OD25 outputs - 25mA sink/source (O25) or 25mA sink-only (OD25) for direct interface with MOSFET gates or logic buffers. |
Pinout & Package
UTC2000-I/MG is housed in a 3 × 3 × 0.9 mm 16-pin QFN package with exposed thermal pad connected to VSS. Pin 14 and 15 are no-connect (NC); exposed pad must be soldered to ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OCS# | Fault input | Active-low system fault signal (e.g., overcurrent) that forces all outputs to default state and asserts FAULT_IND. |
| CFG_SEL | Mode configuration | Analog input sampled at power-on to select DFP (Legacy/1.5A/3.0A) or UFP mode; DFP profile changes dynamically. |
| ENABLE | Controller enable | Active-high input enabling state machine; device remains inactive if low or floating (tie to VDD via 10kΩ). |
| FAULT_IND | Fault indicator | Active-high open-drain output asserted during OCS# or VMON overvoltage faults; cleared only by reset/power cycle. |
| AUDIO_ADAPTER/CONNECTED# | Mode-dependent indicator | DFP: active-high audio adapter detection; UFP: open-drain connection status (low = valid Type-C link with VBUS in range). |
| CC1 / CC2 | USB Type-C configuration channel | ADC inputs monitoring CC line voltages to detect plug insertion, orientation, Rd/Ra presence, and charging capability. |
| VCONN1_OUT# / VCONN2_OUT# | VCONN supply control | DFP-only open-drain outputs enabling 5V VCONN supply to CC1 or CC2 for active cables (low = enabled). |
| PLUG_ORIENTATION# | Orientation indicator | Active-low output indicating cable flip: high = Rd on CC1 (unflipped), low = Rd on CC2 (flipped). |
| VMON | VBUS monitor input | ADC input scaling VBUS (via resistor divider); >0.8V triggers overvoltage fault; required in UFP, tied to GND in DFP if unused. |
| PPC_EN | Port power control | DFP-only active-high output enabling 5V VBUS supply switch; asserted only after valid Type-C connection detection. |
| VDD / VSS | Power / Ground | VDD: 4.5–5.5V supply with 0.1µF bypass capacitor; VSS: ground reference and thermal pad connection point. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable DFP/UFP mode | Single CFG_SEL pin selects operational role at power-on; DFP supports runtime switching between Legacy/1.5A/3.0A profiles. |
| Plug orientation detection | Dedicated PLUG_ORIENTATION# output eliminates need for host MCU polling of CC1/CC2 to determine cable flip state. |
| VCONN-powered cable support | Two independent open-drain VCONN control outputs (VCONN1_OUT#, VCONN2_OUT#) enable selective 5V supply to active cables. |
| USB audio adapter detection | AUDIO_ADAPTER output signals CC1+CC2 short-to-ground condition, enabling automatic DP/DM ↔ audio path switching. |
| VBUS overvoltage protection | VMON input with 0.8V threshold provides hardware-level VBUS monitoring independent of host firmware. |

FAQ
What is the primary function of the UTC2000-I/MG in a USB Type-C design?
The UTC2000-I/MG is a dedicated USB Type-C controller IC that handles physical-layer detection and control tasks including CC1/CC2 monitoring, plug orientation identification, VCONN supply management, audio adapter detection, and VBUS overvoltage monitoring. It enables rapid integration of USB Type-C receptacles into USB 2.0/3.0 DFP or UFP systems without requiring complex firmware or additional analog components. The UTC2000-I/MG reduces design risk by offloading critical USB Type-C protocol decisions to hardware.
How does the UTC2000-I/MG determine whether it operates in DFP or UFP mode?
The UTC2000-I/MG determines its operational mode at power-on by sampling the analog voltage on the CFG_SEL pin. A voltage between 0.0V–0.3V, 0.7V–0.8V, or 1.2V–1.3V configures it as a DFP with Legacy, 1.5A, or 3.0A charging profile respectively; 1.75V–VDD configures it as a UFP. Once powered up, DFP mode allows dynamic switching between charging profiles, but UFP↔DFP transitions require a full power cycle - the UTC2000-I/MG does not support runtime role swapping.
Can the UTC2000-I/MG support USB Audio Adapter detection, and how is it implemented?
Yes, the UTC2000-I/MG supports USB Audio Adapter detection in DFP mode via its AUDIO_ADAPTER output pin. It identifies adapters by sensing Ra pull-down resistors on both CC1 and CC2 lines - a condition functionally equivalent to shorting both CC pins to ground. When detected, the UTC2000-I/MG asserts AUDIO_ADAPTER high to trigger external high-speed USB/audio switches. This hardware-level detection eliminates the need for host MCU polling or custom firmware logic, making the UTC2000-I/MG suitable for plug-and-play audio accessory support.
What happens when the VMON pin exceeds 0.8V, and how does the UTC2000-I/MG respond?
When the VMON pin voltage exceeds 0.8V - corresponding to VBUS >6.4V - the UTC2000-I/MG immediately enters fault state: all digital outputs revert to their default inactive levels (e.g., PPC_EN low, PLUG_ORIENTATION# high), and FAULT_IND is driven high. This fault flag persists until a power-on reset or full power cycle occurs; toggling ENABLE does not clear it. In UFP mode, VMON is mandatory; in DFP mode, it must be tied to GND via 10kΩ if unused. This behavior ensures fail-safe response to overvoltage conditions without MCU intervention.
Does the UTC2000-I/MG require external components for basic USB Type-C functionality?
Yes, the UTC2000-I/MG requires external components for full operation: Rp or Rd pull-up/down resistors on CC lines depending on DFP/UFP role, a 0.1µF bypass capacitor on VDD, and a 10kΩ pull-up on ENABLE if left uncontrolled. For DFP applications, external 5V port power switches (controlled by PPC_EN) and VCONN FETs (driven by VCONN1_OUT#/VCONN2_OUT#) are needed. No external ADC, level shifters, or USB PHYs are required - the UTC2000-I/MG integrates all necessary analog front-end and logic for basic Type-C control.
