PC33999EK Datasheet 16-output Switch With Spi And Pwm Control

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33999 Rev 1.0, 01/2004 Preliminary Information 16-Output Switch with SPI and PWM Control The 33999 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. Eight parallel inputs are also provided for direct Pulse Width Modulation (PWM) control of eight dedicated outputs. Additionally, an output-programmable PWM input provides PWM of any bination of outputs. A dedicated reset input provides the ability to clear all internal registers and turn all outputs off. The 33999 directly interfaces with microcontrollers and is patible with both 3.3 V and 5.0 V CMOS logic levels.
