STGAPSiCS: Galvanically Isolated Gate Driver with Dual Input Pins for Safe Control of SiC MOSFETS
![STGAP2SiCS Galvanically Isolated 4A Gate Driver](/sites/default/files/components/STGAP2SiCS.jpg)
STMicroelectronics has introduced the STGAPSiCS, 4A Galvanically isolated gate driver for safe control of silicon carbide (SiC) MOSFETs and operates from a high-voltage rail up to 1200V. The STGAP2SiCS is capable of producing gate-driving voltage up to 26V and can have a raised Under-Voltage Lockout (UVLO) threshold of 15.5V to meet the turn-on requirements of SiC MOSFETs. The driver features dual input pins that let designers determine the gate-drive signal polarity.
The STGAP2SiCS provides 6kV of galvanic isolation between the input section and the gate-driving output. This ensures safety in consumer and industrial applications. Its 4A output-sink/source capability is suited to mid-and high-power converters, power supplies, and inverters in equipment such as high-end home appliances, industrial drives, fans, induction heaters, welders, and UPSes.
The input circuitry is compatible with CMOS/TTL logic down to 3.3V, which allows easy interfacing with a wide variety of control ICs. The total delay is less than 75ns, permitting accurate pulse-width modulation (PWM) control up to high switching frequencies. Matched propagation delays between the low-voltage and high-voltage sections prevent cycle distortion and minimize energy losses. Available at a price point of $2.00 in the quantities of 1000 units, the STGAP2SiCS is housed in a wide-body SO-8W package that ensures 8mm creepage within a compact footprint.
