SLUSBO6C JANUARY 2014 – October 2018 TPS40425
PRODUCTION DATA.
Format | Linear | ||||
Description | The READ_IOUT command returns the output current in amps for each channel. The reading from the Measurement System must be manipulated in order to convert the measured value into the desired value (IOUT). Note: only positive currents are reported. Any computed negative current (For example, 0 measured current and –4 A IOUT_CAL_OFFSET) is reported as 0 A.
READ_IOUT is a paged register. In order to access READ_IOUT register for channel 1 of the TPS40425 device, PAGE[7],[0] must be set to 00. In order to access READ_IOUT register for channel 2 of TPS40425 controller, PAGE[7],[0] must be set to 01. PAGE[7],[0] register cannot be set to 11 for READ_IOUT command. The temperature compensation factor used for IOUT_CAL_GAIN in reporting READ_IOUT is fixed to 3900 ppm/°C. |
