Description
TAB

bat
Supply Voltage
The backside TAB is connected to the power supply of the
MC33288DH. In addition to its supply function, this pin 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 6,7,8 are the source of the output1 25mOhm MOSFET1. Pins
13,14,15 are source of the output 2 25mOhm MOSFET2. They deliver
current to the connected loads and 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 MOSFET is in the off state. When input is
high, the MOSFET is turned on and the load is activated.
When both inputs are low, the device is in standby mode and its
supply current is reduced. Each input pin has an internal active pull
down, so that it will not float if disconnected.

Status
Status for both
Channels
The Fault output is an open drain indication that goes active low when
a fault mode (Openload, 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.

Wlp
Warning Lamp Output
This pin is the source of a 3.2 Ohm MOSFET. This output is current
limited and thermally protected. It delivers current through the
connected load when both IN1 and IN2 inputs are logic high. It is usually
used as a warning lamp driver for Flasher application.

Cur R
Load Current Sense
The Current Sense pin deliver a ratioed amount (1/1000) of the sum
of the currents that can be used to generate signal ground referenced
output voltages for use by the microcontroller.
