Evaluation Kit - 33879, Configurable Octal Serial Switch
- このページには、製造中止（生産終了）となった製品の情報が記載されています。本ページに記載されている仕様および情報は、過去の参考情報です。
This EVALUATION KIT supports the MC33879 device, which is an 8-output hardware-configurable, high side/low side switch with 16-bit serial peripheral interface (SPI) 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.
This Evaluation kit may be used with the FRDM-KL25Z. The FRDM-KL25Z can be used as a FRDM SPI Dongle. All other FRDM boards currently online are also compatible with this board.
