TPIC2603DW

TPIC2603DW Description

The TPIC2603DW from Texas Instruments is a low-side power driver IC designed for general-purpose switching applications. Housed in a 24-pin SOIC package, it integrates six outputs with a 1:6 input-to-output ratio, making it ideal for driving inductive or resistive loads. Operating within a 4.5V to 5.5V supply range, it supports load voltages from 5.5V to 25V, delivering up to 350mA per channel. With a low Rds(on) of 1.7Ω (typical), it ensures efficient power handling and minimal heat dissipation. The device features serial interface control, simplifying integration into digital systems while offering robust fault protection including current limiting, open-load detection, over-temperature, and over-voltage safeguards.

TPIC2603DW Features

• Six low-side outputs with 350mA current capability per channel.
• Wide load voltage range (5.5V–25V) for versatile applications.
• Low Rds(on) (1.7Ω) for reduced power loss and improved efficiency.
• Serial interface for easy digital control and daisy-chaining.
• Comprehensive protection: Fixed current limiting, open-load detection, thermal shutdown, and over-voltage protection.
• RoHS3 compliant and REACH unaffected, meeting environmental standards.
• Surface-mount (SOIC-24) packaging for compact PCB designs.

TPIC2603DW Applications

The TPIC2603DW excels in systems requiring multi-channel low-side switching, such as:

• Automotive electronics: Relay/solenoid drivers, lighting controls.
