FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
POWER SUPPLY PINS (VSUP1:VSUP8)
VSUP1:VSUP8 are device power supply pins. The
nominal input voltage is designed for operation from 12 V
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.
All VSUP pins must be connected to get full chip
functionality.
POWER GROUND PINS (GND1:GND4)
GND1:GND4 are device power ground connections.
Owing to the low ON-resistance and current requirements of
the half-bridge driver outputs and high side output drivers,
multiple pins are provided.
GND1 and GND2 pins must be connected to get full chip
functionality.
HALF-BRIDGE OUTPUT PINS (HB1:HB4)
The 908E622 device includes power MOSFETs
configured as four half-bridge driver outputs. The HB3:HB4
have a lower RDS(ON), to run higher currents (e.g. fold motor),
than the HB1:B2 outputs.
The HB1:HB4 outputs are short-circuit and over-
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)
The HS output pins are a low RDS(ON) high side switches.
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
capability using the PWM input.
The HS1 has a lower RDS(ON), to run higher currents (e.g.
heater) than the HS2 and HS3 outputs.
For the HS1 two pins (HS1a:HS1b) are necessary for the
current capability and have to be connected externally.
Important: The HS3 can be only used to drive resistive
loads.
EC GLASS PINS (ECR, EC)
These pins are used to drive the electrochrome function on
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 1.4 V. The output voltage can
be selected by an integrated DA converter.
HALL-EFFECT SENSOR INPUT PIN (H0)
The Hall-effect sensor input pin H0 provides an input for
Hall-effect sensors (2-pin or 3-pin) or a switch.
ANALOG INPUT PINS (A0, A0CST)
These pins are analog inputs with selectable current
source values. The A0CST is intent to trim the A0 input.
WAKE-UP INPUT PIN (L0)
This pin is 40 V rated input. It can be used as wake-up
source for a system wake-up. The input is falling or rising
edge sensitive.
Important: If unused, this pin should be connected to
VSUP or GND to avoid parasitic transitions. In Low Power
mode, this could lead to random wake-up events.
SWITCHABLE VDD OUTPUT PIN (HVDD)
The HVDD pin is a switchable VDD output for driving
resistive loads requiring a regulated 5.0 V supply; e.g., 3-pin
Hall-effect sensors or potentiometers. The output is short-
circuit protected.
LIN BUS PIN (LIN)
The LIN pin represents the single-wire bus transmitter and
receiver. It is suited for automotive bus systems and is based
on the LIN bus specification.
+5.0 V VOLTAGE REGULATOR OUTPUT PIN (VDD)
The VDD pin is needed to place an external capacitor to
stabilize the regulated output voltage. The VDD pin is
intended to supply the embedded microcontroller.
Important The VDD pin should not be used to supply
other loads; use the HVDD pin for this purpose. The VDD,
EVDD and VDDA/VREFH pins must be connected together.
VOLTAGE REGULATOR GROUND PIN (VSS)
The VSS pin is the ground pin for the connection of all non-
power ground connections (microcontroller and sensors).
Important VSS, EVSS and VSSA/VREFL pins must be
connected together.
RESET PIN (RST_A)
RST_A
is the bidirectional reset pin of the analog die. It is
an open drain with pull-up resistor and must be connected to
the RST pin of the MCU.
INTERRUPT PIN (IRQ_A)
IRQ_A
is the interrupt output pin of the analog die
indicating errors or wake-up events. It is an open drain with
pull-up resistor and must be connected to the IRQ pin of the
MCU.
ADC SUPPLY/REFERENCE PINS (VDDA/VREFH
AND VSSA/VREFL)
VDDA and VSSA are the power supply pins for the analog-
to-digital converter (ADC).
VREFH and VREFL are the reference voltage pins for the
ADC.
