KIT33879AEKEVBE

KIT33879AEKEVBE is a MC33879, configurable octal serial switch. This evaluation kit supports the MC33879 device, which is an 8-output hardware-configurable, high-side/low-side switch with 16bit serial peripheral interface (SPI) control. Two of the outputs may be controlled directly via microprocessor for PWM applications. The 33879 incorporates SMARTMOS® technology, with CMOS logic, bipolar/MOS analogue circuitry, and DMOS power MOSFETs. The 33879 controls various inductive, incandescent, or LED loads by directly interfacing with a microcontroller.

• MC33879: configurable octal serial switch, MC33880: octal serial switch with SPI
• 16bit SPI for control and fault reporting, 3.3V / 5.0V compatible
• Designed to operate 5.5V ≤ VPWR ≤ 26.5V
• Outputs are current limited (0.6A to 1.2A) to drive incandescent lamps
• Output voltage clamp, + 45V (low side) and - 20V (high side) during inductive switching
• Internal reverse battery protection on VPWR
• Maximum 5.0µA IPWR standby current at 13V VPWR
• On/off control of open load detect current (LED application)
• Short-circuit detect and current limit with automatic retry, independent over-temperature protection
• Loss of ground or supply will not energize loads or damage IC, RDS(ON) of 0.75ohm at 25 °C typical
