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 m鈩?and two 40 m鈩? and an integrated
IC control die consisting of eight low-side drivers (600 m鈩?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 direct input.
The 33888 is available
in
two power packages.
