TEMPERATURE SENSE GAIN
The analog multiplexer can be configured via SPI to allow the
ADOUT0 pin to deliver the internal junction temperature of
the device.
The graph below illustrates the internal chip temp sense
obtained per characterization at 3 temperatures with 3
different lots and 30 samples.

HIGH SIDE OUTPUT PINS HS1
This output is one high side driver intended to drive small
resistive loads or LEDs incorporating the following features:
? PWM capability (software maskable)
? Open load detection
? Current limitation
? Over-temperature shutdown (with maskable interrupt)
? High-voltage shutdown (software maskable)
? Cyclic sense
The high side switch is controlled by the bit HS1 in the High
Side Control Register (HSCR).
PWM Capability (direct access)
The high side driver offers additional (to the SPI control)
direct control via the PWMIN pin.
If the bit HS1 and PWMHS1 are set in the High Side Control
Register (HSCR), then the HS1 driver is turned on if the
PWMIN pin is high and turned of if the PWMIN pin is low.
