OPERATIONAL MODES
The graph below illustrates the internal chip temp sense
obtained per characterization at 3 temperatures with 3
different lots and 30 samples.
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 high side switches are controlled by the bits HS1:2 in
the High Side Control Register (HSCR).
HIGH SIDE OUTPUT PINS HS1 AND HS2
These outputs are two high side drivers intended to drive
small resistive loads or LEDs incorporating the following
features:
PWM Capability (direct access)
Each high side driver offers additional (to the SPI control)
direct control via the PWMIN pin.
• PWM capability (software maskable)
• Open load detection
If both the bits 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.
This applies to HS2 configuring HS2 and PWMHS2 bits.
• Current limitation
• Over-temperature shutdown (with maskable interrupt)
• High-voltage shutdown (software maskable)
• Cyclic sense
