FUNCTIONAL DESCRIPTION
INTRODUCTION
FUNCTIONAL DESCRIPTION
INTRODUCTION
The MC33288DH is a dual high side switch with
appropriate control, protection, and diagnostic features
dedicated to automotive flasher applications. The device
consists of two independent 25mW power switches and an
W warning lamp. It interfaces directly with a microcontroller
and the package used is a 20-HSOP power small outline, 20
terminals. The MC33288 incorporates a status terminal and
a load current sense capability.

FUNCTIONAL TERMINAL DESCRIPTIONS
SUPPLY VOLTAGE (VBAT)
The backside TAB is connected to the power supply of the
MC33288DH. In addition to its supply function, this terminal
contributes to the thermal behaviour of the device by
conducting the heat from the switching MOSFET to the
printed circuit board.
OUTPUT CHANNEL (OUT1, OUT2)
Pins 6, 7, and 8 are the source of the output 1 25 m ?
MOSFET1. Pins 13, 14, and 15 are the source of the output
2 25 m ? MOSFET2. They deliver current to the connected
loads and are controlled via the IN1 and IN2 terminals,
respectively . These outputs are current limited and
thermally protected.
LOAD CURRENT SENSE (CUR R)
The Current Sense terminal delivers 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.
INPUT CHANNEL 1/2 (IN1, IN2)
These are the device input terminals 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 terminal has an internal active pull-down, so that
it will not float if disconnected.
GROUND (GND)
This is the ground terminal of the device.
STATUS FOR BOTH CHANNELS (STATUS)
The Fault output is an open drain indication that goes active
low when a fault mode (Openload, Overtemperature) is
detected by the device on either one channel or both
channels simultaneously. Its internal structure is an open
drain architecture with an internal clamp at 6.0 V. An
external pull-up resistor connected to V DD (5.0 V) is needed.
WARNING LAMP OUTPUT (WLP)
This terminal is the source of a 3.2 ? 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.
