PC33880

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33880/D Rev 1, 09/2002 Advance Information Configurable Octal Serial Switch with Serial Peripheral Interface I/O The 33880 device is an eight output hardware configurable high side/low side switch with 8-bit serial input control. Two of the outputs may be controlled directly via microprocessor for PWM applications. The 33880 incorporates SMARTMOS™ technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The 33880 controls various inductive or incandescent loads by directly interfacing with a micro controller. The circuit’s www.DataSheet4U.com innovative monitoring and protection features include: very low standby currents; cascade fault reporting; internal +40 V clamp voltage for low side configuration; -20 V high side configuration; output specific diagnostics; and independent shutdown of output. Features Designed to operate 5.5 V < VPWR < 24.5 V 8-Bit SPI for Control and Fault Reporting, 3.3 V/5.0 V Compatible Outputs are current limited (0.8 A to 2 A) to Drive Incandescent Lamps Output voltage Clamp, +45 V (low side) and -20 V (high side) During Inductive Switching Internal Reverse Battery Protection on VPWR Loss of Ground or Supply Will Not Energize Loads or Damage IC Maximum 5 µA IPWR Standby Current at 13.0 V VPWR RDS(ON) of 0.55Ω at 25°C Typical Short Circuit Detect and Current Limit with Automatic Retry Independent Over Temperature Protection 28-Lead SOIC Cas...
