Double Pulse Testing in driver DEBUG Mode (w/o SPI communication)
4.4.1
Enabling DEBUG Mode
The evaluation gate driver board is designed with the new automotive EICEDriver Sense/Boost ICs. These come
with a high number of programmable features (via SPI communication). For first evaluation tests, like double
pulse testing, a SPI communication is preferred but not mandatory. The IC has an option called “DEBUG MODE”
which can be enabled at power up and allows afterwards an operation similar to typical gate drivers with basic
functions.
Figure 6 Removing the 0R resistor bridge (marked on the PCB) at each gate driver channel enables the
DEBUG mode at next power up cycle. The gate driver is then ready to be used without SPI communication
in a basic configuration without advanced features.
Please note: The 0R resistor bridge and SPI communication is required when the board is used in the HybridKIT
inverter mode. Without SPI communication the logicboard will stop operation as NTC temperature reading and
ADC functions for DC-voltage measurement are not working.
