From headlights to taillights, and everything in between, TI’s portfolio of integrated smart high-side switches provide advanced protection and diagnostics for your automotive applications.
Integrated current sense accuracy enables real-time monitoring for open-load and short-to-battery detection without any calibration needed, ultimately reducing production cost and test time.
Smart High-Side Switches from TI protect against Short-to-GND and short-circuit events through the flexibility to select current limit values for targeted thresholds. This also allows you to reduce PCB traces and connector sizes, lowering system costs.
In automotive and industrial applications, designers use a switch in the power line to control energy transition to loading systems. This power switch requires low on-resistance and high voltage tolerance in order to sustain the voltage spike and current inrush during system operation. Previously, a simple MOSFET could be used for this, but as safety concerns and intelligence requirements rise, more sophisticated devices must be used to provide diagnostic and protective functions.
TI’s TPSxHxxx family of high-side switches provide a rich feature set and advanced specifications to eliminate the challenge of working with discrete components to simplify system design and speed up the design cycle.
Today, power switches are implemented using two topologies: high-side and low-side. A high-side switch controls applying power, while a low-side switch governs the GND connection. Adoption is shifting from low side to high side.
TI’s portfolio of smart high-side switches provide a variety of advantages, including:
