MC33879TEK中文资料Switch, Congifurable 8 Channels, SOIC 32数据手册恩XP规格书

描述 Description

The NXP® MC33879 device is an 8-output hardware configurable, high side/low side switch with 16-bit serial input control using the serial peripheral interface (SPI).
Two of the outputs may be controlled directly via a MCU for pulse-width modulation applications
Incorporates SMARTMOS® technology with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs
Controls various inductive, incandescent, or LED loads by directly interfacing with a MCU
We recommend the use of the \"A\" version devices for new designs

特性 Features
