The NXP USA Inc. MC33888FB is a high-performance power switch IC featuring 12 outputs, configurable as four high-side and eight low-side switches. This device offers robust fault protection, including fixed current limiting, open load detection, and over-voltage protection. Its integrated watchdog timer enhances system reliability. The MC33888FB utilizes an SPI interface for flexible control and diagnostics. With low on-state resistances of 10mOhm, 40mOhm, and 600mOhm, it minimizes power dissipation. The component operates across a wide voltage range, supporting loads from 6V to 27V and a supply voltage of 4.5V to 5.5V. It is housed in a 64-PQFP (14x14) surface-mount package, suitable for demanding applications in automotive and industrial sectors. Operating temperature range is -40°C to 150°C (TJ).
