NOTES :
In case of over current or short-circuit, the device will not report the fault to the status pins. The output current will be limited to the Ilim value. The device will probably
heat up and in this case the overtemperature detection will be triggered. If so, the output will be turned off and the fault will be reported to the status pins.

DEVICE DESCRIPTION
Input
Introduction
The MC33288ADH is a dual high side switch with
In-1 and In-2 are the two inputs of the device, connected to
a microcontroller I/O ; they are CMOS compatible. When
these inputs are in low state, the device is in standby mode as
described above. When any of the inputs are switched to a
high level, the associated output MOSFET is turned on.
appropriate control, protection, and diagnostic features
dedicated to automotive flasher applications. The device
consists of two independent 25mΩ power switches and an
additionnal 3.2 Ohm high side switch capable of controlling a
1.2W warning lamp. It interfaces directly with a microcontroller
and the package used is a HSOP20 power small outline, 20
pins. The MC33288A incorporates a status pin and a load
current sense capability.
Status
The device has a single status pins which reports an over
temperature and an openload condition in the device. This pin
is an open drain structure and needs an external pull up
resistor. The device incorporates overtemperature sense on
each output MOSFET in order to independently protect each
output. But , the report of the overtemperature is done through
one single status pin called St, in order to minimise the
number of I/O connection of the MCU.
Power Supply
The MC33288A can be directly connected to the supply
line. In standby mode (In-1 & In-2 @ OV), the supply current is
less than 10µA for Vbat supply voltage below 14V. This
feature allows a very low supply current on the battery when
the car is idle or parked.
The device is activated by the switching to a high level of
the In-1 or In-2 input pin. During off state, the current recopy
pin and the status pins are in high impedance.
Open Load Function
The open load detection is active during the ON phase (Hot
open load detection). An amplifier measures the differential volt-
The MC33288A is self protected against reverse battery
up to -24 Volts in a continuous mode. When a negative battery
voltage arises, the MOSFETS are internally turned on. The
load current flows in reverse in each MOSFET.
age between V and V
.
bat
out
An open load condition will create a voltage lower than 30mV
and the open load circuitry will detect it and will pull down the sta-
tus output. If the open load condition is present before the device
turn-on, the status will be pulled down after a delay due to the rise
time of the output.
Power Output Switches
The device has two independent high side switches. Each
switch is realised with N-channel power MOSFET and
includes current and temperature sensing circuitries. The
MOSFET gates are driven by an analog circuitry which
includes charge pump and fault detection. A specific feature
of this device is the output current recopy.
Each output has a 25mΩ Rdson at 25°C, the Rdson value
reaches 40mΩ at 150°C junction temperature. Each output
has a parasitic drain to source diode, inherent to the
technology. This diode can sustain as much current as the
MOSFET. This diode is reversed biassed during normal
operation of the MOSFET and is forwarded biassed during
reverse battery or negative transient pulses.
The output MOSFET can drive 8 Amps nominal. This is
the maximum current in the flasher application. This
maximum current condition occurs when up to three 21W
lamps and two small 5 or 7W lamps are connected on each
channel, at higher Vbat voltage specification. This is the case
when a trailor is attached to the car. This value takes also into
account the usual lamps tolerances. As the flasher can
operate in warning or hazard operation mode with its two
channels on, the MC33288 can drive 16 Amps total.
Current Recopy Function
Flasher application needs to detect failed lamp. The
system must detect one 21W lamp failing, in the flasher
application only, without a trailor. The MC33288 has an output
current recopy function which recopies on the Cur R pin a
portion of the output current. Each channel is connected to the
same Cur R pin as the system have to operate in the flasher
mode only and not in the warning operation.
The MC33288A provides a current recopy of 1/1000 of the
main output current, either output left or right. The recopy
function has its higher accuracy of +-10% in the usual
operation range and an accuracy of +-20% in the total
operating range. This allows a precise detection of one 21W
lamp, but also the detection of additional lamps in case of
trailor connection.
An external resistor must be connected to the Cur R pin
and then tied to a microcontroller A/D input for analog voltage
measurement. The Cur R pin is internally clamped to protect
the MCU A/D input.
Nominal Voltage and Transient Operation
When lamps are turned on, the inrush current can reach
up to 6 times the nominal lamp current. For this particular
application, the total inrush current can reach 6 time 8 Amps,
that is up to 48Amps per channel. The 48Amps value will only
occur at the first lamp turn on. In order to optimise the total
system,(MC33288, printed circuit board, wiring, fuse etc.) the
device incorporates a current limitation at 30 Amps typical.
This mean that the really first inrush current will be clamped at
30 Amps. The second lamp turn on of the flashing cycle will
not see any clamping as the lamps have been heated up in the
previous cycle. It has to be noted that the nominal current
occurs at 14V battery voltage, with only 2*21W and 5W as
load which ends up to a 5Amps nominal current, being
30Amps peak in rush current.
The nominal operation voltage is from 9 to 16V. The
MC33288A is functional over a larger voltage range from 8V
to 35V. The technology used for both power and analog
circuitry sustains 40V DC voltage.
During reverse battery operation or negative transient
pulses, the power MOSFET will be turned on and both the
MOSFET and the Drain to Source Body Diode will drive the
output current limited by the load only.
The MC33288ADH is not protected in case of loss of
digital ground. If this feature is needed, it is necessary to add
few external component (see application note) or it is advised
to use the MC33288DH.

Thermal Management
A more complete model including thermal capacitance is
proposed in figure 3.
The junction to case thermal resistance is 2°C/W
maximum. The junction to ambient thermal resistance is
dependent on the mounting technology and the addition of
heat sink. One of the most commonly used mounting
technique consists in using the printed circuit board and the
copper lines as heat sink.

With the above layout, thermal resistance junction to ambient
of 25°C/W can be achieved, this value being splitted into :
• junction to case : Rthjc1 = Rthjc2 = 2°C/W
• case to ambient : Rthca = 23 °C/W.

Lower value can be reached with the help of larger and
thicker copper metal, higher number of thermal via from top to
down side pcb and the use of additional thermal via from the
circuit board to the module case.

Steady State Thermal Model
The junction to ambient thermal resistance of the circuit

main parts : junction to case and case to ambient resistances.
A simplified steady state model is shown in figure 2.
