MC33888FB

The MC33888FB is a type of single-package integration of a power die with four discrete high-side MOSFETs (two 10 m and two 40 m) and an combine IC control die including eight low-side drivers (600 m each) with appropriate control, protection, and diagnostic features.

Features of MC33888FB are: (1)dual 10 m high side, dual 40 m high side, octal 600 m low side; (2)full operating voltage of 6.0 v to 27 v; (3)SPI Control of high-side overcurrent limit, high side current sense, output off open load detection, output on/off control, watchdog timeout; (4)SPI reporting of program status and fault; (5)high-side analog current feedback with selectable ratio; (6)enhanced 16V reverse polarity vpwr protection.

The electrical characteristics of the MC33888FB can be summarized as: (1)supply voltage range(fully operational): 6. 0V min and 27V max; (2)VPWR supply current(TJ> 125°C): 17mA typ and 25mA max; (3)logical supply sleep state current: 5.0uA max; (4)overvoltage shutdown threshold: 28.5V min, 32V typ and 36V max; (5)overvoltage shutdown hysreresis: 0.2V min, 0.6V typ and 1.5V max; (6)undervoltage high-side output shutdown: 5.0V min, 5.6V typ and 6.0V max, etc.
