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.

Features

• Output voltage clamp of +50V during inductive switching
• On/Off control of open load detect current (LED application)
• VPWR standby current < 10μA
• RDS(ON) of 0.55Ω at 25°C typical
• Independent over-temperature protection
• Output selectable for PWM control
• Output ON short-to-VBAT and off short-to-ground/open detection
• Pb-free packaging designated by suffix code EK
