PINS FUNCTION DESCRIPTION
Dual High Side Switch for H-Bridge Automotive Applications

Pin No.
Name/Function
Description
TAB
V
bat
Supply Voltage
The backside TAB is connected to the power supply of the
MC33486DH. In addition to its supply function, the tab contributes to
the thermal behaviour of the device by conducting the heat from the
switching MOSFET to the printed circuit board.

OUT1
OUTPUT Channel 1
OUT 2
OUTPUT Channel 2
Pins 5, 6,7,8 are the source of the output1 15mOhm High-side
MOSFET1. Pins 13,14,15 are source of the output 2 15mOhm High-side
MOSFET2. They are respectively controlled via the IN1 and IN2 pins.
These outputs are current limited and thermally protected

IN 1
INPUT Channel 1
IN 2
INPUT Channel 2
These are the device input pins which directly control their associated
outputs. The levels are CMOS compatible. When the input is a logic
low, the associated output is low (High Side OFF and Low Side ON).
Each input pin has an internal active pull down, so that it will not float
if disconnected.
19
St
Status for both
Channels
The Status output is an open drain indication that goes active low
when a fault mode (Short to gnd/Vbat, Overtemp) is detected by the
device on either one channel or both simultaneously. Its internal
structure is an open drain architecture with an internal clamp at 6V.
An external pull up resistor connected to Vdd (5V) is needed. See
Functional Truth Table.

GLS1
GLS2
These pins have to be connected to the gate of each Low Side. When the
input (INx) is logic High, the associated GLS is grounded to turn off the
external FET .
20
Wake
This pin is a digital input . When Wake is a logic low, the device
’
s bias current
draw is at a minimum. If Wake is a logic high, the part is operationnal. Wake
pin has a pull down resistor.

Cur R
Load Current Sense
The Current Sense pin deliver a ratioed amount (1/3700) of the sum
of the High Side currents that can be used to generate signal ground
referenced output voltages for use by the microcontroller.
9, 10, 11, 12,
NC
Not Connected
These pins are not used.

GND
GROUND
This is the Ground pin of the device.
