概述

Description

BTS611L1 is a single-channel smart high-side switch (Infineon BTS family) for automotive power applications. It integrates a power MOSFET and protection features to drive a load from a vehicle’s supply without a mechanical relay.
Key points:
- Functions as a controlled high-side switch for loads like lamps, motors, or actuators.
- Built-in protections: overcurrent/short-to-ground protection, thermal shutdown, undervoltage and overvoltage protection, reverse-polarity protection, and open-load detection.
- Diagnostic feedback: provides fault/status signals to the microcontroller for monitoring.
- Simple interface: a control input to turn the load on/off and a diagnostic output for MCU integration.
- Designed for automotive 12V environments (with a broad supply range), compact packaging suitable for PCB mounting.
Use when you need safe, reliable switching with protection and diagnostics without relays.

Features

Key features of BTS611L1 (single-channel smart high-side switch):
- One-channel high-side switch with integrated current limiter
- Automotive-grade input range suitable for battery voltages
- Protection: short-circuit to ground or VBAT, overvoltage, undervoltage
- Thermal shutdown with auto-retry
- Reverse polarity protection
- Inrush/inrush-current control (soft-start)
- Inductive-load protection
- Enable/disable control input
- Diagnostic feedback for fault conditions (open-load, overcurrent, thermal/UV/OV)
- Suitable for inductive loads; compact package and wide operating temp range

Package

The BTS611L1 comes in an 8-lead PowerSSO-8 (surface-mount) package.

Pinout

Pin count: 6 pins.
Function: BTS611L1 is a 6‑pin automotive high‑side load switch with current limiting and protection features. It switches VBATT to the load under control of an input (enable/control), providing overcurrent/thermal protection and diagnostic output for fault indication. Package commonly SOT-23-6.

Manufacturer

Manufacturer: Infineon Technologies AG.
What kind of company: A German multinational semiconductor manufacturer and systems provider (headquartered near Munich) that designs and produces microelectronics and power semiconductors for automotive, industrial, and security applications.

Application

Primary application areas of BTS611L1: Automotive electrical system protection and controlled DC load switching (high-side), used for LED headlamps/taillamps, interior/exterior lighting, power windows/mirrors and seat actuators, smart power distribution and load-switching in ECUs; Industrial and consumer DC load switching for motors, solenoids, pumps, and lighting where reverse polarity, overcurrent, overvoltage, and thermal protections are required.
