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 mand two 40 mΩ) and an integrated
IC control die consisting of eight low-side drivers (600 meach) 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.
Features
• Dual 10 mHigh Side, Dual 40 mHigh Side, Octal 600 mLow Side
• Full Operating Voltage of 6.0 V to 27 V
• SPI Control of High-Side Overcurrent Limit, High Side Current Sense,
Output OFF Open Load Detection, Output ON/OFF Control, Watchdog
Timeout
• SPI Reporting of Program Status and Fault
• High-Side Analog Current Feedback with Selectable Ratio
• Enhanced 16 V Reverse Polarity VPWR Protection
