33888A
33888A is Quad High-Side and Octal Low-Side Switch for Automotive manufactured by Motorola Semiconductor.
features
. Programming, control, and diagnostics are acplished 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
- 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
