DEVICE DESCRIPTION
INTRODUCTION
The 33289 is a dual high-side switch with appropriate
control, protection, and diagnostic features dedicated to drive
inductive loads such as solenoid drivers for automotive and
industrial applications. The device consists of two independent
applications with two independent 40 m
power switches. It
can be linked directly with a microcontroller. It is available in a
SOICW 20 surface mount package.
Power Supply
The 33289 can be directly connected to the supply line. In
Standby mode (in-1 and in-2 at 0V), the supply current is less
than 5.0 μA for V
BAT
supply voltage below 14 V. This feature
allows a very low supply current on the battery, for example,
when an auto is idle or parked. During OFF state, the status
pins are in high impedance. In case of loss of (digital) ground,
the power MOSFETs turn OFF in order to safely tie the load
current to zero.
Nominal Voltage and Transient Operation
The nominaloperationvoltage isfrom6.0 to 26 V.The33289
device is functional over a larger voltage range from 6.0 V to
27V. The technology used for both power and analog circuitry
sustains 40 V DC voltage.
Power Output Switches
The device has two independent high-side switches. Each
switch is realized with an N-channel power MOSFET and
includes current and temperature sensing circuitries. The
MOSFET gates are driven by analog circuitry which includes
charge pump and fault detection.
Each output has a40 m
R
DSON
maximum 25°C. The R
DSON
value reaches 75 m
at 150°C junction temperature. Each
output has a parasitic drain to source diode, inherent to any
verticalMOSFET.Thisdiodecansustainasmuchcurrent atthe
MOSFET. The diode is reversed biased during normal
operation of the MOSFET and is forward biased during reverse
battery, or negative transient pulses.
Status
The device has an independent status pin per output,
reporting an overtemperature, overcurrent, and an open load
condition in the device. This pin is an open drain structure,
requiring an external pull-up resistor. The device incorporates
overtemperature sense on each output MOSFET in order to
independently protect each output.
Open Load Function
The open load detection is active during the OFF phase, or
cold open load detection. An amplifier measures the differential
voltage between V
BAT
and V
OUT
.
When the load current is below 400 mA, the open load
circuitry will pull down the status output. The open load circuitry
can be disabled with the OLDE to ensure very low standby
current.
Package
The device is assembled into a surface mount package.
