ANALOG DIE INPUTS/OUTPUTS
High-Side Output Terminals HS1 and HS2
These are two high-side switches used to drive loads such
as relays or lamps. They are protected with overtemperature
and current limit (overcurrent) and include an active internal
clamp circuitry for inductive load drive. Control is done using
the SPI Control register. PWM capability is offered through
the PWMIN input terminal.
The high-side switch is turned on if both the HSxON bit in
the SPI Control register is set and the PWMIN input is HIGH
PWMIN must be HIGH and bit HS1ON must be set. The
same applies to the HS2 output.
If no PWM control is required, PWMIN must be connected
to the VDD terminal.
Current Limit (Overcurrent) Protection
These high-side switches feature current limit to protect
them against overcurrent and short circuit conditions.
Overtemperature Protection
If an overtemperature condition occurs on any of the three
high-side switches, the faulty switch is turned off and latched
off until the HS1 (or HS2 or HS3) bit is set to “1” in the SPI
Control register. The failure is reported by the HSST bit in the
SPI Control register.
Sleep and Stop Mode
In Sleep and Stop modes the high-sides are disabled.
High-Side Output HS3
This high-side switch can be used to drive small lamps,
Hall-effect sensors, or switch pullup resistors. Control is done
using the SPI Control register. No direct PWM control is
possible on this terminal (refer to Figure 13, page 24).
Current Limit (Overcurrent) Protection
This high-side feature switch feature current limit to protect
it against overcurrent and short circuit conditions.
Overtemperature Protection
If an overtemperature condition occurs on any of the three
high-side switches, the faulty switch is turned off and latched
off until the HS3 (or HS1 or HS2) bit is set to “1” in the SPI
Control register. The failure is reported by the HSST bit in the
SPI Control register.
Sleep and Stop Mode
In Sleep and Stop mode the high-side is disabled.
