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.
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
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.
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.
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 .
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.
of the High Side currents that can be used to generate signal ground
referenced output voltages for use by the microcontroller.
These pins are not used.
This is the Ground pin of the device.
The Current Sense pin deliver a ratioed amount (1/3700) of the sum
