MCZ33999EK中文资料Low-Side Switch, 16 Channels, SOIC 54数据手册恩XP规格书

描述 Description

The NXP® MC33999 is a 16-output low-side switch with a 24-bit serial input control, designed for a variety of applications including inductive, incandescent, and LED loads.
The SPI provides both input control and diagnostic readout
Eight parallel inputs are also provided for direct PWM control of 8 dedicated outputs
An output programmable PWM input provides PWM of any combination of outputs
A dedicated reset input provides the ability to clear all internal registers and turn all outputs off
Interfaces with MCUs and compatible with both 3.3 V and 5.0 V CMOS logic levels
Serves as a bus expander and buffer with fault management features, reducing the MCU fault management burden
