Infineon Smart High Side Power Load Switch SIPMOS SOIC-20

Infineon Smart High Side Power Load Switch is a SOIC-20 power management IC built with Smart SIPMOS technology. It offers a 5.5V to 40V operating voltage range and a 6.5A current limit, and is intended for demanding automotive and industrial applications.

Overview

The device integrates four N-channel vertical power MOSFETs with a charge pump and ground-referenced CMOS-compatible inputs. It is designed to handle a wide variety of 12V and 24V grounded loads, including resistive, inductive and capacitive types. It is particularly well suited to loads with high inrush currents, such as lamps.

The switch is intended as an alternative to electromechanical relays, fuses and discrete circuits, which can help save space and improve system reliability.

Protection Features

The device includes embedded protective functions to support safe and stable operation:

• Short-circuit protection
• Overload protection with current limitation
• Thermal shutdown
• Overvoltage protection, including load dump, configurable with external resistors
• Reverse battery protection, configurable with external resistors
• Loss of ground and loss of Vbb protection

Diagnostics and Operational Control

An open-drain diagnostic output provides system information. It enables open-load detection when the switch is off and feedback when a thermal shutdown event occurs during operation, supporting system monitoring and fault management.
