The NXP® MC33879APEKR2 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 MCU for pulse-width modulation applications
- Incorporates SMARTMOS® technology with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs
- Controls various inductive, incandescent, or LED loads by directly interfacing with a MCU
- We recommend the use of the "A" version devices for new designs
Feature
- Designed to operate 5.5 V ≤ VPWR ≤ 27.5 V
- 16-bit SPI for control and fault reporting, 3.3 V / 5.0 V compatible
- Outputs are current limited (0.6 A to 1.2 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 µA IPWR standby current at 13 V VPWR
- RDS(ON) of 0.75 Ohm at 25 °C typical
- Short-circuit detect and current limit with automatic retry
- Independent over-temperature protection
- The MC33879 is included in NXP®.s product longevity program, with assured supply for a minimum of 15 years after launch
