33879
Preliminary Information
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 shutdown of output.
Features
Designed to Operate 5.5 V < VPWR < 26.5 V
16-Bit SPI for Control and Fault Reporting, 3.3 V/5.0 V Compatible
Outputs Are Current Limited (0.5 A to 1.5 A) to Drive Incandescent
Lamps
Output Voltage Clamp, +45 V (Low Side) and -20 V (High Side) During
Inductive Switching
On/Off Control of Open Load Detect Current (LED Application)
Internal Reverse Battery Protection on VPWR
Loss of Ground or Supply Will Not Energize Loads or Damage IC
Maximum 5.0
A IPWR Standby Current at 13.0 V VPWR
RDS(ON) of 1.0 at 25°C Typical
Short Circuit Detect and Current Limit with Automatic Retry
Independent Overtemperature Protection
CONFIGURABLE OCTAL SERIAL
SWITCH WITH OPEN LOAD
