INFINEON Smart High Side Power Load Switch, SIPMOS Technology, SOIC-20

The INFINEON Smart High Side Power Load Switch (BTS716GXUMA1) is an advanced power management IC designed for demanding automotive and industrial applications. This device integrates four N-channel vertical power MOSFETs with a charge pump, ground-referenced CMOS-compatible inputs, and comprehensive diagnostic feedback, all built using monolithically integrated Smart SIPMOS® technology. It serves as a robust and intelligent high-side switch, offering significant advantages over traditional electromechanical solutions.

Core Features and Advantages

This switch is engineered to handle a wide variety of 12V and 24V grounded loads, including resistive, inductive, and capacitive types, and is particularly well-suited for loads with high inrush currents such as lamps. It effectively replaces electromechanical relays, fuses, and discrete circuits, saving space and improving system reliability.

A key benefit is its extensive suite of embedded protective functions, which ensures safe and stable operation. These include short-circuit protection, overload protection with current limitation, and thermal shutdown. The device also offers overvoltage protection (including load dump) and reverse battery protection, both configurable with external resistors, alongside loss of ground and loss of Vbb protection.

Diagnostic and Operational Control

The integrated diagnostic feedback with an open-drain output provides critical system information, enabling open-load detection when the switch is off and feedback when a thermal shutdown event occurs during operation. This allows for sophisticated system monitoring and fault management.
