NXP Semiconductors 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 pulsewidth 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,...
