MC33880 Datasheet | Motorola Semiconductor

Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33880/D Rev 3.0, 01/2004 Advance Information Configurable Octal Serial Switch with Serial Peripheral Interface I/O The 33880 device is an eight-output hardware configurable high-side/lowside 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 microcontroller. The circuit’s innovative monitoring and protection Features include very low standby currents, cascade fault reporting, 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 patible - Outputs Are Current Limited (0.8 A to 2.0 A) to Drive Incandescent Lamps - Output Voltage Clamp Is +45 V (Typical) (Low-Side Drive) and -20 V (Typical) (High-Side Drive) During Inductive Switching - Internal Reverse Battery Protection on VPWR - Loss of Ground or Supply Will Not Energize Loads or Damage IC - Maximum 5.0 µA IPWR Standby Current at 13 V VPWR up to 95°C - RDS(ON) of 0.55 Ω at 25°C Typical - Short Circuit Detect and Current Limit with Automatic Retry - Independent Overtemperature Protection - 32-Pin SOIC Has Pins 8, 9, 24, and 25 Grounded for Thermal Performance CONFIGURABLE OCTAL SERIAL SWITCH WITH SERIAL PERIPHERAL INTERFACE Freescale Semiconductor, Inc...
