33879A Configurable octal serial switch

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 338.

33879A 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 overtemperature protection.
