Advance Information
Dual High-Side Switch 40 mΩ
The 33289 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.
33289
This device consists of two independent 40 mΩ RDSON MOSFET
channels plus corresponding control circuitry in a surface mount
package. The 33289 can be interfaced directly to a microcontroller for
input control and monitoring of diagnostic output.
DUAL HIGH-SIDE SWITCH
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.

Definition
VBAT
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 behavior of the
device in conducting the heat from the switching MOSFET to the printed circuit
board.
1, 2, 5, 6, 15, 16,
19, 20
OUTPUT Channel 1 Pins 3 and 4 are the output 1 pins. Pins 17 and 18 are the output 2 pins. They are
3, 4, 18, 17
OUT1
OUT2
directly connected to the source of the power MOSFET. These pins are used by
OUTPUT Channel 2
the control circuitry to sense the device output voltage. The RDSON is 40 mΩ max
per output at 25°C and will increase to a maximum of 75 mΩ at 150°C junction
temperature.
INPUT Channel 1
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.
8, 13
IN1
IN2
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 for Channel 1 These pins are the channel 1 and channel 2 fault detection flags. Their internal
9, 12
ST1
ST2
structure is an open drain architecture with an internal clamp at 6.0 V. An external
Status for Channel 2
pull up resistor connected to VDD (5.0 V) is needed. This is an active low 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.
Open Load Detection This pin is a digital input which enables the open load current diagnostic circuitry.
10
11
OLDE
GND
Enable
When OLDE is a logic low, the open load circuitry is not powered 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 higher bias current draw. OLDE pin has a pull down
resistor.
GROUND
This is the GND pin of the device.
