MCZ33996EKR2

MCZ33996EKR2 is a 16-output low-side switch with a 24-bit serial input control. It is designed for a variety of applications including inductive, incandescent, and LED loads. The Serial Peripheral Interface (SPI) provides both input control and diagnostic readout. A Pulse Width Modulation (PWM) control input is provided for pulse width modulation of multiple outputs at the same duty cycle. A dedicated reset input provides the ability to clear all internal registers and turn all outputs off. It is directly interfaced with microcontrollers and is compatible with both 3.3 and 5.0V CMOS logic levels. The 33996, in effect, serves as a bus expander and buffer with fault management features that reduce the MCU’s fault management burden.
