Technical Data
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 using the serial peripheral
interface (SPI). Two of the outputs may be controlled directly via a
microcontroller for pulse-width modulation (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 5.5 V < V PWR < 26.5 V
? 16-bit SPI for control and fault reporting, 3.3 V / 5.0 V compatible
? Outputs are current limited (0.6 to 1.2 A) to drive incandescent
lamps
