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  
Pin No.  
Name/Function  
bat  
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 40mmax per output at 25°C and  
will increase to a maximum of 75mat 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 channelstatus flag will be pulled low. See  
Functional Truth Table.  
Status for Channel 1  
St2  
Status for Channel 2  
10

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 devices 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.
