Safe Status Channel 1 Output. Programmable active-high or active-low. SAFE1 asserts when
programmed channel 1 temperature threshold or current threshold has been reached.
I
SPI mode, drive A0/CSB low to select the device.
Active-Low Conversion-Start Input. Drive CNVST low to start a conversion (clock modes 01 and 11).
Connect CNVST to DV
Mode Select. Connect SEL to DGND to select I
Alarm Output. Program ALARM for comparator or interrupt output modes (see the Alarm Modes
section). Program ALARM to assert on any combination of channel temperature or current
thresholds.
Safe Status Channel 2 Output. Programmable active-high or active-low. SAFE2 asserts when
programmed channel 2 temperature threshold or current threshold has been reached.
No Connection. Not internally connected.
