POWER SUPPLY PINS (VSUP1: VSUP8)
nominal input voltage is designed for operation from 12V
systems. Owing to the low ON-resistance and current
requirements of the half-bridge driver outputs and high side
output drivers, multiple VSUP pins are provided.

POWER GROUND PINS (GND1:GND4)
Owing to the low ON-resistance and current requirements of
the half-bridge driver outputs and high side output drivers,
multiple pins are provided.

temperature protected, and they feature current recopy. Over
current protection is done on both high side and low side
FET’s. The current recopy are done on the low side
MOSFETs.
HIGH SIDE OUTPUT PINS (HS1:HS3)
Each HS switch is protected against over-temperature and
over-current. The output is capable of limiting the inrush
current with an automatic PWM or feature a real PWM

EC GLASS PINS (ECR, EC)
EC glass mirrors. The ECR pin is used to connect an external
ballast resistor. The EC pin provides the mirror with an
regulated output voltage up to 1.4V. The output voltage can
be selected by an integrated DA converter.
HALL-EFFECT SENSOR INPUT PIN (H0)
Hall-effect sensors (2pin or 3pin) or a switch.
