Product details
Overview
TCPP03-M20 from STMicroelectronics is a USB-C Power Delivery 3.1 companion controller designed to interface with STM32 microcontrollers featuring integrated UCPD peripherals. It provides dual-role power (DRP) support up to 100 W (20 V/5 A SPR), embedded N-MOSFET gate drivers for consumer/provider paths, 24 V tolerance on VBUS and CC pins, and integrated VBUS/VCONN discharge. It enables cost-effective, MCU-based USB-C PD implementations in portable chargers and DRP-enabled docking stations.
For engineers reviewing the TCPP03-M20 datasheet, TCPP03-M20 pinout, TCPP03-M20 application, or TCPP03-M20 equivalent, this device is selected for its I²C-configurable OVP/OCP thresholds (1.16 V typical VOVP_TH on Vsense, 42 mV typical VTH_OCP_VBUS), dual-gate-driver architecture, dead-battery management, and USB-IF certified operation on X-NUCLEO-DRP1M1-G4 (TID6408).
Technical Context
The TCPP03-M20 operates as a hardware protection and signal conditioning companion to STM32 UCPD-capable MCUs - not a standalone PD controller. Its functional block integrates independent gate drivers (GDPg/GDCg), analog current sensing (Isense → IANA with 42 V/V gain), and configurable protection logic (OVP on VBUS at 1.16 V threshold, OCP at 42 mV across sense resistor), all managed via I²C with two selectable addresses (0x64/0x65).
It supports three I²C-controlled power modes: Hibernate (dead-battery enabled, FLGn indicates VBUS presence), Low Power (CC clamped at 5 V, no PD communication), and Normal (full performance, failure flagging via FLGn). VBUS turn-on time is 1–3 ms; OVP response is ≤145 ns; OCP reaction is 3–8 µs - enabling fast fault containment in bidirectional power paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBUS OVP Threshold | 1.16 V on Vsense pin - sets 20 V OVP at 20:1 external resistor divider; enables precise, adjustable overvoltage cutoff before MCU damage |
| VBUS OCP Threshold | 42 mV across Rs - triggers shutdown at 5 A with 10 mΩ sense resistor; supports 100 W SPR compliance |
| VCONN OCP | 47 mA typical trip - protects 5 V VCONN supply against short circuits while maintaining USB-C spec-compliant 1 W delivery |
| I²C Address | 0x64 or 0x65 - LSB set by I2C_ADD pin (GND or 1.8/3.3 V); allows dual-device addressing on same bus without conflict |
| CC Pin ESD Rating | ±8 kV contact / ±15 kV air (IEC 61000-4-2 Level 4) - meets USB-C robustness requirements with external 100 nF CBIAS capacitor |
| Thermal Shutdown | 150 °C typical - disables gate drivers and asserts FLGn to prevent thermal runaway during sustained overload |
| VBUS Discharge Time | 220 ms - safely drains 20 V/100 µF bus capacitance via internal 2.5 kΩ path; eliminates residual voltage hazards |
Pinout & Package
TCPP03-M20 uses a QFN-20L package (4.0 × 4.0 × 0.75 mm) with exposed thermal pad (GND). The pinout supports full USB-C DRP functionality with separate gate drive, current/voltage sense, and dual CC channel routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CC1 / CC2 | UCPD interface (MCU side) | Low-voltage (≤5.5 V) differential signaling inputs/outputs connected directly to STM32 UCPD peripheral |
| CC1c / CC2c | USB-C connector interface | 24 V-tolerant CC pins with integrated 5.75 V OVP clamp and ESD protection; require external 100 nF CBIAS |
| GDPg / GDPs | Provider path gate driver | GDPg drives gate of external N-MOSFET; GDPs returns source node - enables low-Rds(on) sourcing with cost-effective N-FETs |
| GDCg / GDCs | Consumer path gate driver | GDCg drives sink-path N-MOSFET gate; GDCs returns source - supports bidirectional power with independent control |
| VSENSE / ISENSE | VBUS monitoring inputs | VSENSE measures VBUS voltage via resistor divider; ISENSE connects to shunt for analog current sensing (→ IANA output) |
| IANA | Analog current output | 42 V/V gain output (±2 mV offset) - delivers 1.95 V at OCP event; interfaces directly to MCU ADC without external op-amp |
| FLGn | Open-drain fault flag | Active-low indicator: VBUS presence in hibernate/low-power mode; OVP/OCP/OTP fault in normal mode (requires I²C register read) |
| EN / I2C_ADD | Power enable & address select | EN controls I²C voltage domain (1.8 V or 3.3 V); I2C_ADD sets LSB of 7-bit I²C address (0x64 or 0x65) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent N-MOSFET gate drivers | Enables use of low-cost, low-Rds(on) N-channel FETs instead of P-FETs - reduces BOM cost and board area vs ASIC-based PD solutions |
| Configurable VBUS OVP/OCP thresholds | I²C-adjustable trip points allow system-level tuning for different input sources (e.g., 15 V adapters, 20 V PPS) without hardware change |
| Integrated VBUS/VCONN discharge | On-chip 2.5 kΩ discharge paths eliminate need for external MOSFETs or RC networks - simplifies layout and improves safety certification |
| Dead-battery management | Automatic VBUS detection and wake-up in hibernate mode enables charging from 0 V battery - critical for portable devices with depleted cells |
| USB-IF certified operation | Validated on X-NUCLEO-DRP1M1-G4 (TID6408) - guarantees interoperability with certified chargers, cables, and accessories per USB PD 3.1 |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C PD companion controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TUSB320LAIR | Standalone Type-C port controller with integrated PD PHY; no gate drivers; requires external FETs and discrete OVP/OCP | Targets simpler UFP/DFP-only designs; lacks DRP support and analog current sensing | Select when full PD protocol stack offload is needed and cost-per-FET is less critical than integration level |
| NXP PTN3364B | USB-C redriver/re-timer with limited PD awareness; no VBUS switching, OVP, or gate drivers | Designed for signal integrity enhancement only - not a PD protection or power path controller | Not functionally equivalent; avoid for power delivery control applications |
Compared with TUSB320LAIR and PTN3364B, the TCPP03-M20 uniquely combines MCU companion architecture, dual N-FET gate drivers, analog current sensing (IANA), and USB-IF certified DRP operation - delivering lower system BOM cost and faster fault response for STM32-based designs.

FAQ
What is the purpose of the CBIAS pin?
The CBIAS pin connects to an external 100 nF, 50 V capacitor that forms part of the integrated ESD protection circuit for the CC1c and CC2c pins. This capacitor works with internal clamping diodes to absorb ±8 kV contact and ±15 kV air discharge events per IEC 61000-4-2 Level 4, ensuring robust USB-C connector-side immunity without additional TVS diodes.
How does the TCPP03-M20 support dead-battery operation?
In hibernate mode (ENABLE = low, VCC_VCONN = 0 V), the TCPP03-M20 monitors VBUS through internal UVLO (2.4 V typical) and asserts FLGn to indicate presence of input voltage - allowing the host MCU to wake up and initiate charging even when the system battery is fully depleted. No external biasing or auxiliary power is required.
Can the TCPP03-M20 be used without an STM32 UCPD MCU?
No - the TCPP03-M20 is explicitly designed as a companion device for STM32 MCUs with embedded UCPD peripherals. It lacks a built-in PD protocol engine and relies on the host MCU for PD message handling, policy engine execution, and state machine control via I²C. Standalone PD negotiation is not supported.
What is the maximum VBUS voltage the TCPP03-M20 can tolerate on its pins?
The TCPP03-M20 supports 24 V absolute maximum rating on VBUSc, CC1c, CC2c, GDPs, and GDCs pins per Table 2 of DS13618. This tolerance enables safe operation during transient overvoltage events - such as misconnected 24 V supplies or faulty chargers - while its internal OVP triggers at 20 V (configured via Vsense divider) to protect downstream circuitry.
