This document is a technical data sheet for 33888. It introduces the features and characteristics of 33888, including voltage range, package type, pin definition, etc.
The MC33888 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). It includes appropriate control, protection, and diagnostic features 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, while the low sides share a single configurable direct input.
The device supports a full operating voltage range from 6.0 V to 27 V.
Each high-side output can be controlled via SPI or using its own dedicated parallel input terminal.
