PTC Heaters
Positive temperature coefficient (PTC) heaters provide in-cabin heating to assure passenger comfort, converting stored high voltage power to heat as part of an electric or hybrid electric vehicle’s HVAC system. Skyworks digital isolation, isolated current and voltage sensors, and isolated gate drivers provide the necessary components for high voltage heating system designs with robust efficiency and stable and consistent heat delivery.
Si8932
The SI893x’s 0 to 2.25 V specified input range is ideal for isolated voltage sensing. Flexible output options include differential analog (Si8931) and single-ended analog (Si8932). The Si893x provides excellent linearity with low offset and gain drift to ensure that accuracy is maintained over the entire operating temperature range.
Si823H9
Si823Hx devices are robust gate drivers for silicon-, GaN- or SiC-based power converter systems, such as SMPS or inverters. Features include a robust 30 V driver VDD capability, low latency for tighter loop control, noise filtering; high CMTI of 125 kV/µs, -5 V voltage withstand on output pins and over-temperature protection.
Si88342
Si88xx integrated products for signal and power isolation are complete isolation solutions, combining high speed digital isolators with an isolated power supply. These products are ideal for applications like industrial automation, programmable logic controllers (PLC), battery management systems, and motor control that require long-term performance.
