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.

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.

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. 1 The reverse battery is optional. Remove T1, D2, R2 and connect –Mot to Gnd to remove the features. 3 www.irf.com © 2014 International Rectifier Submit Datasheet Feedback August 14, 2014 Automotive Grade 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  Vifbk  gnd min  Ratio min Imax appli  Offset Vifbk  gnd max Ishtd 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.) 4 www.irf.com © 2014 International Rectifier Submit Datasheet Feedback August 14, 2014 AUIR33402S Automotive Grade In pin and digital diagnostic The IN has two functions. In normal working condition, the output follows the IN pin digital level.
