PD-95807 RevB IR3101 Series 1.6A, 500V Half-Bridge FredFet and Integrated Driver Description IR3101 is a gate driver IC integrated half bridge FredFET designed for sub 250W (heat-sink-less) motor drive applications. The sleek and compact single-in-line package is optimized for electronic motor control in appliance applications such as fans and compressors for refrigerators. The IR3101 offers an extremely compact, high performance half-bridge inverter, in a single isolated package for a very simple design for twophase and three-phase motor drivers. Proprietary HVIC and latch immune CMOS technologies, along with the HEXFET® power FredFET® technology (HEXFET® with ultra-fast recovery body diode characteristics), enable efficient and rugged single package construction. Propagation delays for the high and low side power FredFETs are matched thanks to the advance IC technology. Features • Output power FredFets in half-bridge configuration • High side gate drive designed for bootstrap operation • Bootstrap diode integrated into package. • Lower power level-shifting circuit • Lower di/dt gate drive for better noise immunity • Excellent latch immunity on all inputs and outputs • ESD protection on all leads • Isolation 1500 V RMS min Absolute Maximum Ratings Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation are measured under board mounted and still air conditions.

Electrolytic bus capacitors should be mounted as close to the module bus terminals as possible to reduce ringing and EMI problems. Additional high frequency ceramic capacitor mounted close to the module pins will further improve performance. 2. In order to provide good decoupling between Vcc-VSS and VB-VO terminals, a capacitor connected between these terminals is recommended and should be located very close to the module pins. Additional high frequency capacitors, typically 0.1µF, are strongly recommended. 3. Low inductance shunt resistor should be used for phase leg current sensing. Similarly, the length of the traces from the pin to the corresponding shunt resistor should be kept as small as possible. 4. Value of the bootstrap capacitors depends upon the switching frequency. Their selection should be made based on IR design tip DN 98-2a or Figure 8. 5. Application conditions should guarantee minimum dead-time of 200ns 6 www.irf.com IR3101 3.00 Low Side MOSFET High Side MOSFET Maximum output current [A]. 2.50 2.00 1.50 HS 1.00 LS 0.50 IO 0.00 0 2 4 6 8 10 12 14 16 18 20 Switching Frequency [kHz] Figure 3: Maximum phase current as function of switching frequency Trapezoidal modulation, 120° switching, VBUS=300V, Duty Cycle=0.8, without heatsink: Ta=55°C, TJ=150°C 3.00 Low Side MOSFET High Side MOSFET Maximum output current [A]. 2.50 2.00 1.50 HS 1.00 LS 0.50 IO 0.00 0 2 4 6 8 10 12 14 16 18 20 Switching Frequency [kHz] Figure 4: Maximum phase current as function of switching frequency Trapezoidal modulation, 120° switching,VBUS=300V, Duty Cycle=0.8, with heatsink: TC=100°C, TJ=125°C www.irf.com 7 IR3101 9.75 450 7.75 Current (A) 400 Current Voltage 350 6.75 300 5.75 250 4.75 200 3.75 150 2.75 100 1.75 50 0.75 0 -0.25 Voltage (V) 8.75 -50 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 Time (µs) Figure 5.
