BTS5215L – Intelligent High-Side Power Switch for Automotive Distributor, Dual-Channel 12V Load Protection

The BTS5215L is an intelligent high-side power switch designed for automotive power distribution systems.
It features two independent output channels, each capable of driving resistive, inductive, and capacitive loads.
This chip is ideal for replacing relays and discrete circuits in body control modules and junction boxes.

Each channel includes embedded protection against overcurrent, overtemperature, and short circuit to ground.
The device provides very low standby current, minimizing battery drain when the vehicle is off.
It operates from 5.5V to 40V, making it compatible with 12V and 24V truck electrical systems.

Diagnostic feedback is available through a status flag pin, indicating fault conditions like thermal shutdown or open load.
The BTS5215L supports inrush current management for lamp and motor loads.
Built-in inductive load clamping allows safe driving of relays, solenoids, and small actuators.

This power switch reduces PCB space by integrating two channels in a single small package.
It is suitable for powering turn lamps, stop lights, HVAC blowers, washer pumps, and seat heaters.
Operating temperature range spans -40°C to +150°C for reliable performance under harsh conditions.

Use the BTS5215L for automotive aftermarket repairs or new electronic control unit designs.
It simplifies wiring and improves system reliability compared to traditional discrete solutions.
