Infineon BTT60502EKAXUMA1: A High-Performance Smart High-Side Power Switch

In the realm of automotive, industrial, and consumer electronics, efficient and robust power management is paramount. The Infineon BTT60502EKAXUMA1 stands out as a premier solution, representing a significant leap in smart high-side switch technology. This device integrates advanced protection features, diagnostic capabilities, and high efficiency into a single, compact package, making it an ideal choice for driving resistive, capacitive, and inductive loads.

Exceptional Performance and Integration

Housed in a space-saving PG-TO-252-5 (DPAK) package, the BTT60502EKAXUMA1 is designed to handle demanding applications. Its core is built upon Infineon's proven PROFET™ (Protected MOSFET) technology. This chip is a single-channel, smart high-side switch capable of controlling outputs with a nominal voltage of 24 V and a continuous current of up to 1.7 A. The integration of a vertical power MOSFET with a charge pump and comprehensive protection circuitry simplifies design-in, reduces board space, and enhances system reliability.

Advanced Protection and Diagnostic Features

What truly defines this device as "smart" is its extensive suite of embedded protection and diagnostic functions. It is engineered to safeguard both itself and the connected load against a wide array of fault conditions. Key protections include:

Overload and Short-Circuit Protection: The switch automatically limits the output current in case of an overload or short to ground, preventing thermal destruction.

Overvoltage Protection (e.g., Load Dump): It can withstand voltage transients common in automotive environments, protecting the system from voltage spikes on the supply line.

Overtemperature Protection: An integrated temperature sensor shuts down the device if the junction temperature exceeds a critical threshold, reactivating only once it has cooled down.

Reverse Battery Protection: The chip is inherently protected against a reversed supply voltage, eliminating the need for an external series diode and its associated power loss.

Furthermore, it provides precise diagnostic feedback to the microcontroller via a dedicated status pin. This enables real-time monitoring of conditions such as open-load (both ON-state and OFF-state), short to ground, and overtemperature pre-warning. This level of diagnostics is crucial for developing predictive maintenance strategies and ensuring functional safety.

Optimized for Automotive and Beyond

As an AEC-Q100 qualified component, the BTT60502EKAXUMA1 meets the stringent quality and reliability requirements for automotive applications. It is perfectly suited for controlling a diverse range of loads, including LEDs, solenoids, valves, motors, and heaters. Its low standby current and very low typical on-state resistance (RDS(on)) of just 160 mΩ contribute to high efficiency and minimal power dissipation, which is essential for energy-sensitive and thermally constrained designs.
