Description
D2Pak - 7 leads
The AUIR33402S is a 7 terminals high side switch for variable
speed DC motor. It features simplify the design of the DC
motor drive with a microcontroller. The Mosfet switches the
power load proportionally to the input signal duty cycle at the
same frequency and provides a current feedback on the Ifbk
pin. The over-current shutdown is programmable from 10A to
33A. Over-current and over-temperature latch OFF the power
switch, providing a digital diagnostic status on the input pin. In
sleep mode, the device consumes less than 10uA.
Further integrated protections such as ESD, GND and Cboot
disconnect protection guarantee safe operation in harsh
conditions of the automotive environment.

Automotive Grade
Design: basic schematic with micro-processor
The basic circuit is giving all the functionality to drive a motor up to 33A DC. RIfbk set both the level current shutdown and
the current feedback reading scale. The IN signal provides to the AUIR33402S the Pwm duty cycle. D1 is the free
wheeling diode during PWM operation. As the equivalent circuit between Vbat and – Mot is 2 diode in series (the body
diode of the AUIR33402S and D1), the system requires T1, D2, R1 and R2 to sustain the reverse battery.

This is the recommended schematic with an optional reverse battery1. The recommended load is an inductive load. This
part may not be suitable for application conditions other than those specified above. Please contact IR’s Automotive
Technical support for further details on other applications requirement.
DC to 20 kHz operation
The AUIR33402S is able to operate in DC and high speed switching operation. To be able to switch at 20 kHz, a
bootstrap capacitor is used externally. The device integrates the power supply of the bootstrap capacitor. In DC operation,
when the capacitor is discharged, the charge pump maintains the device ON.

AUIR33402S
Active dv/dt control to reduce EMI Typical Connection
The AUIR33402S includes a special gate drive, managing the Mosfet dv/dt controlled internally, by managing the gate
voltage dynamically. To have the best compromise between the EMI levels and power loss, during the turn on and off
phase, the dv/dt output is dv/dt is not linear. The output voltage shape is an “S” shape.
Sense Load current feedback and programmable current shutdown
The Ifbk pin allows an analog measurement of the load current and with an external resistor allows to program the over
current shutdown level from 10A to 33A. The voltage threshold level of the Ifbk pin is internally set to 4V (See the formulas
below). It is also possible to dynamically adjust the current shutdown protection versus time by adding some external
components. This protection is latched. The operating mode is recovered after resetting by the sleep mode.
Rifbk 

 Ratio min

Vifbk  gnd max

 Ratio max  Offset
Rifbk calculated
Where:
Imax appli is the maximum application current
Ishtd max is the maximum output shutdown current
Internal over current shutdown
The maximum current shutdown threshold value is internally fixed to 50A typ. This protection is latched. The operating
mode is recovered after resetting by the sleep mode.
Under voltage lock-out
The AUIR33402S remains operational from UV Lo threshold. Under this continuous voltage, the device will be locked until
the voltage recovers the operating range, according to an internal hysteresis fixed to 0,5V min. The maximum rating
voltage is given by the Trench VDMOS technology where the avalanche voltage is up to 43V typically.
Sleep mode and reset fault:
The sleep mode is enabled if the IN pin stay low (Vin < Vin µpower) more than Tslp time. The consumption in sleep mode is
Icc off. The AUIR33402S wakes up at first rise edge on the IN pin (Vin > Vin µpower). This mode allows resetting all the
latched faults. (Cf. Figure 2: Wake sequence, sleep mode and reset latched fault.)
Wake up sequence:
The AUIR33402S has a power on reset. After wake up it by the IN signal, the devices wait for Tpwr_on_rst before activate the
output power mosfet. This time is necessary to charge properly the bootstrap capacitor and to stabilize the internal power
supply. (Cf. Figure 2: Wake sequence, sleep mode and reset latched fault.)

In pin and digital diagnostic
The IN has two functions. In normal working condition, the output follows the IN pin digital level. In latched fault condition
(over current and over temperature shutdown), the IN pin provides a digital frequency signal feedback to the µ-processor.
