Texas Instruments TPS25846-Q1 | Demoboard TPS25846Q1EVM-117
Automotive USB Type-C™ DFP controller and power switch
Overview
| Topology | Buck Converter |
| Input voltage | 6-36 V |
| Output 1 | 2.5 V / 3.5 A |
| IC revision | A |
Description
The TPS25846Q1EVM-117 is an evaluation module (EVM) for TI's TPS25846-Q1 USB BC1.2 5-V, 3.5-A output, 36-V input synchronous buck with cable compensation. The EVM operates over a range from 6 V to 36 V and provides USB type A connectors to evaluate USB BC1.2 and USB2.0 data communication functions. The value of cable compensation, current limit, and switching frequency can be adjusted by resistors on the EVM.
Features

- Optimized for power applications
- Integrated I2C control for TI battery chargers
- Web-based GUI and pre-configured firmware
- Optimized for power consumer only (sink) (UFP) applications
- Optimized for power provider (source) and power consumer (sink) (DRP) applications
- USB Type-C power delivery (PD) controller
- 10 configurable GPIOs
- BC1.2 charging support
- USB PD 3.0 compliant
- USB Type-C specification complaint
- Cable attach and orientation detection
- Integrated VCONN switch
- Physical layer and policy engine
- 3.3-V LDO output for dead battery support
- Power supply from 3.3 V or VBUS source
Typical applications
- Automotive: Infotainment, USB hubs, aftermarket USB chargers
