Texas Instruments SN6501-Q1 | Demoboard TIDA-01255

Automotive low-noise, 350-mA, 410-kHz transformer driver for isolated power supplies

Overview

TopologyFull-Bridge Converter symmetrical isolated
Switching frequency410-620 kHz
IC revisionE1

Description

The TIDA-01255 design is built for isolated CAN communication, which is widely used in automotive environments. In hybrid and electric vehicles (HEV/EVs), a complete high-voltage network is floating with respect to the chassis ground. Isolation is required for the power and communication channels interfaced between floating high- to low-voltage systems. The TIDA-01255 design supports applications with a simple isolated transformer driver to transfer power. This TI Design has a low-transmission delay, which reduces the loop delay and supports higher baud rates of the CAN.

Features

  • Flexible high-speed CAN communication
  • Low loop delay (typically 136 ηs) to support high-speed arbitration rates
  • 750-mW power transfer with 3-kV isolation
  • ±70-V bus fault protection
  • Compliant with ISO 11898-2 CAN standard

Typical applications

  • Cell Supervision Systems
  • Hybrid Electric Vehicles (HEV/EVs)
  • Battery Control Units
