This shunt measurement is referenced to the Vcc (measurement on the battery line). Thanks to the shunt value and an external divider resistor, the user can adjust the maximum current in the motor. The internal threshold is Vth Isd. This protection is latched so the Flt output is activated (High state) to provide a diagnostic to the µP. This protection can be reset by activating Flt_rst high for more than Trst time. This protection works only in the motor mode. Tp & Vss, over temperature protection: The IR3230 has CTN interface input: Tp, Vss. This CTN is referenced to the Vss. Thanks to an external resistor in series with the CTN resistor; the user can adjust the maximum temperature threshold. The internal threshold is Vth Tsd. This protection is latched so the Flt output is activated (high state) to provide a diagnostic to the µP. This protection can be reset by activating Flt_rst high for more than Trst time. Mot/Regen: This digital input allows selecting the motor mode or the regeneration mode (braking mode). The µP needs to implement a delay to switch from one to the other to avoid shoot through short circuit and activate the over current fault. This can be calculating by using the “Td xxx xx” parameters in the Switching electrical characteristics. Use the following parameters as a simple rule: Delay to go from the motor mode to the regen mode: use the maximum of the Td2 MtoR Hox off + the maximum of the Tf2_Hox-Vsx parameter. Delay to go from the regen mode to the motor mode: use the maximum of the Td1 RtoM Lox off + the maximum of theTf Lox parameter. Pwm: In motion mode, through the pwm input, the µp controls the speed of the motor. This input provides duty cycle and the frequency to the low side switches in order of the sensor table selected by logical sensor input. In regen mode (buck converter operation), It provides the duty cycle and the frequency to the 3 low side switches in same time independently of the sensor input sequence. So the µP can controls the regeneration current level in the battery and breaking the motor. En: The input Pin enable allows switching off all output power Mosfets and the Charge pump. This reduces the consumption of the device. The Out_supply output stays active to power supply the µP even if the Enable is set at 0V. En pin high wake up the device. When the voltage of charge pump capacitor reaches the UV pump threshold, the device wait for the power reset (Pwr on rst) and then it is ready to operate. 120/60°: This digital input selects the right sensor table in order to the sensor electrical position 120° or 60°. Out_supply: This output provides a 1.6mA regulated current. This output can be used as a biasing to create a power supply thanks to an external zener diode and a bipolar ballast transistor. The created voltage of this power supply is defined by the value of the zener diode implemented. This power supply could be used to supply all external circuitries (Sensor, µP…). Rev/Fwd: This digital input selects the right sensor table in order to choose the motor direction forward and reverse. www.irf.com 14 IR3230 SPbF Fault: A minimum pull down resistor to gnd must be used to limit the current on this output. Please refer to the Absolute maximum ratings table. There is no internal pull down: value is undefined when not in fault if no external pull down resistor is used. Refer to Fault table to check witch event will be latched or not. www.irf.com 15 IR3230SPbF Parameters curves: 140 500 I Hox Vcc 450 I Hox in 400 Low side gate current in mA High side gate current in mA 120 I Hox Gnd 100 80 60 40 20 0 350 300 250 200 150 100 I Lox 50 I Lox in 0 -50 -25 0 25 50 75 100 125 150 -50 -25 0 25 Temperature in °C 50 75 100 125 150 Temperature in °C Figure 1: High side gate current vs. temperature Figure 2: Low side gate current vs. temperature 7,2 88 V Hox -Vsx 86 V Lox 6,8 84 Vth Isd in mV Output Gate voltage in V 7,0 6,6 6,4 6,2 6,0 82 Vth Isd 80 78 76 74 5,8 -50 -25 0 25 50 75 100 125 150 Temperature in °C Figure3: Output temperature www.irf.com gate voltage -50 -25 0 25 50 75 100 125 150 Tj, junction temperature in °C vs. Figure4: Vth Isd Vs Tj 16 IR3230 SPbF Package outline: www.irf.com 17 IR3230SPbF C CARRIER TAPE DIMENSION FOR 28SOICW Metric Imperial Code Min Max Min Max A 11.90 12.10 0.468 0.476 B 3.90 4.10 0.153 0.161 C 23.70 24.30 0.933 0.956 D 11.40 11.60 0.448 0.456 E 10.80 11.00 0.425 0.433 F 18.20 18.40 0.716 0.724 G 1.50 n/a 0.059 n/a H 1.50 1.60 0.059 0.062 www.irf.com 18 IR3230 SPbF REEL DIMENSIONS FOR 28SOICW Metric Imperial Code Min Max Min Max A 329.60 330.25 12.976 13.001 B 20.95 21.45 0.824 0.844 C 12.80 13.20 0.503 0.519 D 1.95 2.45 0.767 0.096 E 98.00 102.00 3.858 4.015 F n/a 30.40 n/a 1.196 G 26.50 29.10 1.04 1.145 H 24.40 26.40 0.96 1.039 www.irf.com 19 IR3230SPbF Part Marking Information Ordering Information Base Part Number IR3230SPBF www.irf.com Standard Pack Package Type SOIC28W Complete Part Number Form Quantity Tube/Bulk 25 IR3230SPBF Tape and Reel 1000 IR3230STRPBF 20 IR3230 SPbF IMPORTANT NOTICE Unless specifically designated for the automotive market, International Rectifier Corporation and its subsidiaries (IR) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or services without notice.

To minimize the risks with customer products and applications, customers should provide adequate design and operating safeguards. Reproduction of IR information in IR data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alterations is an unfair and deceptive business practice. IR is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of IR products or serviced with statements different from or beyond the parameters stated by IR for that product or service voids all express and any implied warranties for the associated IR product or service and is an unfair and deceptive business practice. IR is not responsible or liable for any such statements. IR products are not designed, intended, or authorized for use as components in systems intended for surgical implant into the body, or in other applications intended to support or sustain life, or in any other application in which the failure of the IR product could create a situation where personal injury or death may occur. Should Buyer purchase or use IR products for any such unintended or unauthorized application, Buyer shall indemnify and hold International Rectifier and its officers, employees, subsidiaries, affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that IR was negligent regarding the design or manufacture of the product. Only products certified as military grade by the Defense Logistics Agency (DLA) of the US Department of Defense, are designed and manufactured to meet DLA military specifications required by certain military, aerospace or other applications. Buyers acknowledge and agree that any use of IR products not certified by DLA as military-grade, in applications requiring military grade products, is solely at the Buyer’s own risk and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. IR products are neither designed nor intended for use in automotive applications or environments unless the specific IR products are designated by IR as compliant with ISO/TS 16949 requirements and bear a part number including the designation “AU”. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, IR will not be responsible for any failure to meet such requirements.
