PC33996

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33996 Rev 1.0, 01/2004 Preliminary Information 16-Output Switch with SPI Control The 33996 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. 33996 DUAL OCTAL SERIAL SWITCH WITH SERIAL PERIPHERAL INTERFACE I/O Freescale Semiconductor, Inc... The 33996 directly interfaces with microcontrollers and is compatible with both 3.3 V and 5.0 V 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. Features Designed to Operate 5.0 V < VPWR < 27 V 24-Bit SPI for Control and Fault Reporting, 3.3 V/5.0 V Compatible Outputs Are Current Limited (0.9 A to 2.5 A) to Drive Incandescent Lamps Output Voltage Clamp of +50 V During Inductive Switching On/Off Control of Open Load Detect Current (LED Application) VPWR Standby Current < 10 µA RDS(ON) of 0.55 Ω at 25°C Typical Independent Overtemperature Protection Output Selectable for PWM Control Output ON ...
