BTT6050-1ERA

The Infineon Technologies BTT6050-1ERA is a single-channel smart high-side power switch, integrated into a PG-TDSO-14 package. This device is built using N-channel vertical power MOSFET technology with charge pump, operating within the Smart6 technology. It is specifically engineered for driving loads such as lamps up to 2 * P21W 24V and LEDs in demanding automotive environments.

Key electrical specifications include an operating voltage range of 5V to 36V, a maximum supply voltage of 65V, and a nominal load current of 4.5A. The switch features a typical on-resistance of 50 mΩ, which increases to a maximum of 100 mΩ at 150°C. It also provides a typical current sense ratio of 1:500 and a minimum current limitation of 38A. The device supports 3.3V and 5V compatible logic inputs and exhibits a very low standby current of 0.5 µA at 25°C.

Diagnostic functions include proportional load current sensing, open load detection in both ON and OFF states, and short circuit detection to battery and ground. Protection features encompass overtemperature protection with latch, stable behavior during undervoltage, and voltage-dependent current limitation. The BTT6050-1ERA is designed for applications requiring reliable power switching and diagnostic capabilities in automotive systems.
