Mingjiada Supply TI (TPS2003CDRCR) Dual Channel USB Power Switch

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of TI (TPS2003CDRCR) high-level effective dual-channel 2A load 4.5-5.5V, 70mΩ USB power switches with output discharge and reverse blocking functions.

The following is a detailed technical analysis of the Texas Instruments (TI) TPS2003CDRCR dual-channel current-limited power distribution switch supplied by Mingjiada Electronics, covering product description, specifications, key features, and application scenarios:

1. TPS2003CDRCR Product Description

The TPS2003CDRCR is a dual-channel power distribution switch developed by Texas Instruments (TI), specifically designed for high-capacitive loads and short-circuit protection scenarios. It is particularly suitable for USB power management, industrial control, and consumer electronics devices. The TPS2003CDRCR employs precise current limiting mechanisms to switch to constant current mode during overloads, ensuring the output current remains stable at a safe level and effectively reducing the load on the main power supply. Its core functions include:

Dual-channel independent control: Supports independent switching of two loads, with a maximum output current of 2A per channel.  

Reverse current blocking: Prevents current backflow to protect upstream circuits.  

Fast fault response: Overcurrent response time as low as 2μs (typical value), significantly reducing short-circuit risk.

II. TPS2003CDRCR Specifications and Parameters

Electrical Characteristics

Load voltage range: 4.5V–5.5V; maximum output current: 2A per channel; on-resistance: 70mΩ (typical value).

Package and Physical Characteristics

Package: 10-VSON (3x3); Operating Temperature: -40°C to 125°C (junction temperature); Mounting Method: Surface Mount.  

Protection Features  

Fault Protection: Fixed current limiting (±20% accuracy), over-temperature shutdown, under-voltage lockout (UVLO), reverse current blocking.  

Control Interface  

Input Type: Non-inverting; Switch Control: On/Off (high-level active); Status Indicator: Supports fault status output.

3. TPS2003CDRCR Key Features

Precise current limiting:

Fixed current limit threshold with ±20% tolerance (typical value 3.15A), ensuring predictable current during overloads and preventing power supply failure.

Fast dynamic response:

Overcurrent response time as low as 2μs, with soft-start control reducing switching transient impacts, suitable for high-capacitance load scenarios (e.g., USB ports).

Multiple protection mechanisms:  

Integrated over-temperature shutdown, reverse current blocking, and UVLO enhance system reliability.  

Low-power design:  

No external power supply (Vcc/Vdd) required, extremely low static current, optimising energy efficiency.  

4. Typical application scenarios for the TPS2003CDRCR  

USB power management: USB port protection for laptop computers and desktop peripherals.

Consumer electronics: Load driving and short-circuit protection for HD digital TVs and set-top boxes.

Industrial control: Power distribution switches for PLC modules and motor drive circuits.
