Automotive Power Management ICs (PMICs)

Cypress’s Automotive PMIC solutions are designed to meet the needs of modern ECUs. They are very compact, and are able to tolerate extreme battery voltage fluctuations while providing stable and reliable power. They extend battery life due to their low quiescent current consumption, and they offer features that support System Safety Functions that protect ECU electronics against harsh conditions.

Compact, Low-power, Highly Integrated Automotive Power Management Solution

Industry-leading compact solution

Start-stop systems, along with Load Dump and Cold Cranking conditions, cause extreme battery voltage transients below the voltage that electronic ICs typically utilize. This forces traditional buck type PMICs to use a pre-conditioning filter with bulky, expensive electrolytic capacitors. Cypress’s Automotive PMICs are buck-boost type PMICs that don’t require electrolytic capacitors. Furthermore, they integrate external components such as switching transistors, output voltage setting resistors, and phase compensation circuits. So you get a power management solution that reduces BOM and easily fits into small systems.

Tolerate extreme battery voltage fluctuations with stable and reliable power

Automobile battery voltages can vary from 3 volts up to 35 volts as specified in ISO16750-2. Cypress’s Automotive PMICs tolerate these voltages, while providing stable and reliable power with minimal undershoot and overshoot.

Extend battery life

"Always-on" functions such as keyless entry must continuously operate while the engine is off. Cypress’s Automotive PMICs consume very little power on standby and is extremely battery-friendly.

Support System Safety Functions

ECUs are now used for critical systems. They must be protected against harsh thermal and electrical conditions to ensure proper operation. Cypress Automotive PMICs support System Safety Functions by providing input voltage supervisors, output voltage/current supervisors, thermal management, and watch-dog timers to protect ECUs from damage and erroneous operation.


Cypress’s web-based Easy DesignSim™ simulation and verification tool offers users an automated way to quickly iterate their analog circuit design and generate a bill of materials list. Evaluation kits are also available that will help test and evaluate your design.
