The circuit provides 32 steps of brightness control – from 0 to 100% – for a backlight or instrument panel, using just two general-purpose-microprocessor signals. In addition, the circuit requires little board space, because it uses only three SOT-23s and one µMax package...

STMicroelectronics Introduces High-Voltage Gate Driver 6kV
STMicroelectronics Introduces High-Voltage Gate Driver with 6kV Galvanic Isolation in Compact SO-8W Package
11.03.2020 News

STMicroelectronics’ STGAP2HS is a compact, high-voltage gate driver for applications that require up to 6 kV galvanic isolation between the gate-driving channel and the low-voltage control and interface circuitry. The 1200 V device can sink and source up to 4 A output current to simplify the design...
