Quad High-Side and Octal Low-Side Switch for Automotive The 33888 is a single-package combination of a power die with four
SOLID STATE RELAY FOR
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 AUTOMOTIVE APPLICATIONS 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. Features Dual 10 mΩ High Side, Dual 40 mΩ High Side, Octal 600 mΩ Low Side
