Infineon BTT60101ERAXUMA1 High-Side Switch: Datasheet, Application Circuit, and Key Features

The Infineon BTT60101ERAXUMA1 is a state-of-the-art high-side power switch from Infineon’s PROFET™ (Protected MOSFET) family of smart switches. Designed for robust performance in 12V automotive and industrial applications, this device integrates advanced protection, diagnostics, and control features into a compact package. It is particularly suited for driving resistive, capacitive, and inductive loads such as solenoids, valves, motors, and lamps.

Key Features

One of the standout attributes of the BTT60101ERAXUMA1 is its high current capability, supporting a continuous current of up to 11A. It offers very low standby current and features a diagnostic feedback pin that provides load current information and detects faults such as short circuits to ground or battery, overload, and overtemperature conditions. The device operates with a wide input voltage range from 5.5V to 36V, making it resilient against voltage spikes common in automotive environments. Additionally, it includes reverse battery protection and is designed for low electromagnetic interference (EMI).

Application Circuit

A typical application circuit for the BTT60101ERAXUMA1 is straightforward. The device comes in a DSO-14 package with several pins for power, control, and diagnostics. The input pin (IN) is controlled by a microcontroller GPIO or a logic-level signal to turn the output stage on or off. The sense pin (IS) provides a proportional current output for diagnostics and load current monitoring, often connected to ground via an external resistor. The output pin (OUT) is connected directly to the load. The circuit requires a bypass capacitor between the supply voltage (VS) and ground near the device for stable operation. For inductive loads, a freewheeling diode may be used externally to clamp negative voltage transients.

Datasheet Overview

The datasheet for the BTT60101ERAXUMA1 provides comprehensive details including absolute maximum ratings, thermal characteristics, electrical parameters, and timing diagrams. Key specifications to note are its low on-state resistance (RDS(on)), which ensures high efficiency and minimal heat generation. The document also thoroughly explains the various protection mechanisms and the behavior of the diagnostic output under different fault conditions, which is crucial for designing a fail-safe system.
