TECHNICAL DATA
The MC33289DW is a Dual High Side Switch (DHSS) dedicated for
use in automotive applications. It is designed to drive typical inductive
loads such as solenoid valves.
This device consists of two independent 40mOhm Rdson MOSFET
channels plus corresponding control circuitry in a surface mount
DW SUFFIX
SO20WB Package
CASE 751D-05
package. The MC33289DW can be interfaced directly to
microcontroller for input control and monitoring of diagnostic output.
a
Each switch offers independent protection and diagnosis during
overcurrent, overvoltage, and undervoltage conditions, as well as an
overtemperature shutdown feature.
A logic low on the Open Load Detect Enable pin (OLDE) minimizes
bias current drain by disabling the open load circuitry current source.
The device also has a very low quiescent current in standby mode.

PINS FUNCTION DESCRIPTION

Description
1, 2, 5, 6, 15, 16, 19, 20
V
These are the power supply pins of the device. These pins are
directly connected with the lead frame of the package and are tied to
the drain of the switching MOSFET. These pins can be directly
connected to the battery voltage. In addition to their supply function,
these pins participate to the thermal behaviour of the device in
conducting the heat from the switching MOSFET to the printed circuit
board.
Supply Voltage
3, 4, 18, 17
OUT1
OUTPUT Channel 1
OUT 2
Pins 3 and 4 are the output 1 terminals. Pins 17 and 18 are the output 2
terminals. They are directly connected to the source of the power
MOSFET. These pins are used by the control circuitry to sense the
device output voltage. The Rdson is 40mΩ max per output at 25°C and
will increase to a maximum of 75mΩ at 150°C junction temperature.
OUTPUT Channel 2
8, 13
IN 1
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.
INPUT Channel 1
IN 2
INPUT Channel 2
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.
9, 12
St1
These pins are the channel 1 and channel 2 fault detection flags.
Their internal structure is an open drain architecture with an internal
clamp at 6V. An external pull up resistor connected to Vdd (5V) is
needed. This is an active loaw output. If the device is in its normal
condition the status lines will be high. If open load or other fault
occurs, the associated channel’ status flag will be pulled low. See
Functional Truth Table.

OLDE
This pin is a digital input which enables the open load current diagnostic
Open Load Detection circuitry. When OLDE is a logic low, the open load circuitry is not powered
Enable
and the device’s bias current draw is at a minimum. If OLDE is a logic high,
the open load circuitry is functional at the price of a higherbias current draw.
OLDE pin has a pull down resistor.
GND
This is the Gnd pin of the device.
