Function
Voltage Tracker Output T3 tracked to Q_LDO1; bypass with a
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.
1µF ceramic capacitor for stability. It is switched on and off by
SPI command. Keep open, if not needed.
