Dual-channel 4-A gate driver integrates galvanic isolation and protection features
The STGAP2DM gate driver, the second in the STGAP2 series of galvanically isolated drivers from STMicroelectronics, integrates low-voltage control and interface circuitry with two isolated output channels that allow either unipolar or bipolar gate driving. Rated up to 1700V, the STGAP2DM’s built-in isolation enhances safety as well as simplifying design and saving bill of materials and board […]
Integrated half-bridge lowers motor cost driver complexity
Infineon Technologies AG is launching the IFX007T NovalithIC motor driver for industrial applications. The IFX007T smart half-bridge provides an easy and efficient way to drive brushed and brushless motors, integrating a p-channel high-side MOSFET, an n-channel low-side MOSFET and a driver IC into one package. Along with a microcontroller and power supply, no other devices […]

Automotive-grade 100-V, 4-A half-bridge N-channel MOSFET drivers target hybrid powertrains
Renesas Electronics Corporation announced a new family of automotive-grade 100V, 4A half-bridge N-channel MOSFET drivers. The ISL784x4 family features three devices: the ISL78424 and ISL78444 with single tri-level PWM input for controlling both gate drivers, and the ISL78434, which has dual independent inputs that separately control the high-side and low-side drivers. The ISL784x4 half-bridge N-MOSFET […]
New 650-V gate driver targets motor drive applications below 1 kW
Infineon Technologies AG introduces a new half-bridge, 650 V rated EiceDRIVER based on the company’s unique SOI technology. The 2ED2304S06F provides leading negative VS transient immunity, monolithic integration of a real diode for bootstrap, and superior latch-up immunity. Combined with higher frequency switching, these unique features enable more robust, reliable, smaller systems and reduce BOM […]
Full-bridge 6-kV/3.5-A SiP targets BDC, single-phase brushless motors
STMicroelectronics’ PWD5F60 high-density power driver is the second in a new series of power-driver systems-in-package addressing high-voltage brushed DC and single-phase brushless motor applications. It integrates a 600V/3.5A single-phase MOSFET bridge with gate drivers, bootstrap diodes, protection features, and two comparators in a 15mm x 7mm outline. The thermally efficient system-in-package occupies 60% less board real-estate than […]
