Evaluation Kit | NCV77320R1GEVK

The Evaluation kit is intended for use with the NCV77320 Inductive Position Sensor chip. A Small piggyback sensor board with rotor and two NCV77320 chips is connected to the Evaluation kit. Both chips can be programmed and controlled from the PC GUI via USB.

In Operating mode, it is possible to set the chip to ANALOG or SENT output. If the output is set to ANALOG, the output voltages of the chips are measured by an on−board ADC and send to the GUI, if the output is set to SENT, it is possible to read the position from the output pins through this protocol. Complementary to ANALOG or SENT operation, it is possible to use the SPI interface to access the chip(s) internal registers as well.

In Service mode it is possible to communicate with the chips via the serial interface through the output pin or by SPI. In this mode it is possible to calibrate the chip and program the registers into the EEPROM. The Evaluation kit is operated through a windows−based GUI (Graphical User Interface) and is connected via a USB cable to the microcontroller of the evaluation board. The microcontroller handles the translation from USB to the NCV77320 devices. For the description and capabilities of the NCV77320, refer to the datasheet of this devices.

The Evaluation kit is intended for demonstration of the measurement capabilities of the NCV77320. The kit can be used for first evaluations and is not intended for use at low and high automotive specified temperatures.
