Advance Information  
Quad High-Side and Octal  
Low-Side Switch for Automotive  
33888  
33888A  
The 33888 is a single-package combination of a power die with four  
discrete high-side MOSFETs (two 10 mand 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.  
HIGH-SIDE/LOW-SIDE SWITCH  
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.
