33888A

Quad High-Side and Octal Low-Side

Switch for Automotive

The 33888 is a single-package combination of a power die with four

discrete high-side MOSFETs (two 10 mΩ and two 40 mΩ) and an integrated

IC control die consisting of eight low-side drivers (600 mΩ each) with

appropriate control, protection, and diagnostic features.

SOLID STATE RELAY FOR

AUTOMOTIVE APPLICATIONS

Programming, control, and diagnostics are accomplished using a 16-bit SPI

interface. Additionally, each high-side output has its own parallel input for

pulse-width modulation (PWM) control if desired. The low sides share a single

configurable direct input.

The 33888 is available in two power packages.

Features

• Dual 10 mΩ High Side, Dual 40 mΩ High Side, Octal 600 mΩ Low Side

• Full Operating Voltage of 6.0 V to 27 V

• SPI Control of High-Side Overcurrent Limit, High Side Current Sense,

Output OFF Open Load Detection, Output ON/OFF Control, Watchdog

Timeout

• SPI Reporting of Program Status and Fault

• High-Side Analog Current Feedback with Selectable Ratio

• Enhanced 16 V Reverse Polarity V_PWRProtection
