Product Preview 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.
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 d...
