Function
Ground; to reduce thermal resistance place cooling areas on
PCB close to these pins. The GND pins are connected internally
to the heat slug at the bottom.
SPI Interface Clock input; clocks the shift register; CLK has an
internal active pull down and requires CMOS logic level
inputs;see also chapter SPI
SPI Interface chip select input; CS is an active low input; serial
communication is enabled by pulling the CS terminal low; CS
input should only be switched when CLK is low; CS has an
internal active pull up and requires CMOS logic level inputs ;see
also chapter SPI
SPI Interface Data input; receives serial data from the control
device; serial data transmitted to DI is a 16 bit control word with
the Least Significant Bit (LSB) being transferred first; the input
has an active pull down and requires CMOS logic level inputs; DI
will accept data on the falling edge of CLK-signal; see also
chapter SPI
SPI Interface Data output; this tristate output transfers
diagnosis data to the controlling device; the output will remain 3-
stated unless the device is selected by a low on Chip-Select CS;
see also the chapter SPI
Error output; push-pull output. Monitors failures in parallel to the
SPI diagnosis word, reset via SPI. ERR is an active low, latched
output.
Standby Regulator Output; the output is active even when the
buck regulator and all other circuitry is in off mode
Voltage Tracker Output T1 tracked to Q_LDO1; bypass with a
1µF ceramic capacitor for stability. It is switched on and off by
SPI command. Keep open, if not needed.
Voltage Tracker Output T2 tracked to Q_LDO1; bypass with a
1µF ceramic capacitor for stability. It is switched on and off by
SPI command. Keep open, if not needed.
Voltage Tracker Output T3 tracked to Q_LDO1; bypass with a
1µF ceramic capacitor for stability. It is switched on and off by
SPI command. Keep open, if not needed.
