Advance Information

Document Number: MC33879

Rev 7, 8/2008

Configurable Octal Serial Switch

with Open Load Detect Current

Disable

The 33879 device is an 8-output hardware-configurable, high side /

low side switch with 16-bit serial input control. Two of the outputs may

be controlled directly via microprocessor for PWM applications. The

33879 incorporates SMARTMOS technology, with CMOS logic,

bipolar/MOS analog circuitry, and DMOS power MOSFETs. The 33879

controls various inductive, incandescent, or LED loads by directly

interfacing with a microcontroller. The circuit’s innovative monitoring

and protection features include very low standby currents, cascade

fault reporting, internal + 45 V clamp voltage for low-side configuration,

- 20 V high side configuration, output specific diagnostics, and

independent over-temperature protection.

Features

• Designed to operate 5.5V < V

PWR

< 26.5V

• 16-Bit SPI for control and fault reporting, 3.3V / 5.0V compatible

• 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

• On/Off control of open load detect current (LED application)

• Internal reverse battery protection on V

PWR

• Loss of ground or supply will not energize loads or damage IC

• Maximum 5.0μA I

PWR

standby current at 13V V

PWR

• R

DS(ON)

of 0.75Ω at 25°C typical

• Short-circuit detect and current limit with automatic retry

• Independent over-temperature protection

• Pb-free packaging designated by suffix code EK
