Isolated switches and drivers for insulation resistance monitoring in high-voltage battery packs
Enable highly accurate monitoring and control over high-voltage battery stacks. Our integrated solid-state relays and resources help you create designs for battery pack-passive balancing, battery disconnect unit, battery control unit and wired cell supervisor circuit. Battery pack-passive balancing designs often require:
- Resolution of voltage and temperature measurement on cell level
- Accurate current sense on pack level
Isolated switches and drivers for traction inverters used in EVs for energy recapture in regenerative braking
Our integrated circuits and reference designs allow you to create traction inverter high and low voltage designs that efficiently convert DC power to alternating phases of power to drive multi-phase motors.
Traction inverter high and low voltage designs require:
- Safely and efficiently control and protect the power switch (IGBT/SiC)
- Position sensing of the motor shaft (resolver replacement)
- Following state-of-the-art architecture regarding system redundancy in order to allow implementation of the system on the highest safety level
Isolated switches and drivers for factory automation in programmable logic controller (PLC) applications
Our integrated circuits and reference designs enable you to build PLC equipment such as digital output module, enabling low-side and high-side driving capabilities, push-pull high frequency outputs known as pulse train output (PTO), inductive loads, isolation and protection.
Digital output module designs often require:
- Highly-efficient isolated power supply.
- Advanced protection and diagnostics.
