There are three products depending on power rating of internal high voltage MOSFET listed below: 1) IRDM982-025MB – employs six MOSFET 500V 2A and 600V high voltage IC 2) IRDM982-035MB – employs six MOSFET 500V 3A and 600V high voltage IC All two products are packaged in the 12 x 12 PQFN package and designed to dissipate the power loss through a mating PCB without an external heatsink. All two products contain exactly same control algorithm and analog functions. The controller implements a Hall sensor based control algorithm for 3-phase sinusoidal permanent magnet motor fan applications. The control also employs high efficiency PM motor control algorithm based on a quadratic load curve stored in internal ROM. 16 possible curves are selectable. All devices have an on-chip voltage regulator to derive the 3.3V, required by the digital logic, from the 15V (VCC) supply. The 3.3VDC regulated voltage pin is available externally for connection to Hall-effect sensors. The IC provides low power standby (less than 7mW) mode of operation that 3.3V power is cut off when VSP (Voltage Input) becomes less than 1.15V to provide further power efficient operation. An integrated A/D Converter is used to acquire EFF load curve selection, temperature (internal temp sensing), and the VSP input that sets the voltage applied to the motor. An internal temperature sensor is interfaced to the ADC and resulting digital conversion data is used to control the dynamic overcurrent setpoints as well as max overtemperature limit. The protection functions include a supply under-voltage lockout (3.3V and 15VDC), over-speed protection, over-temperature limit and Over-current limitation protections. The reset circuitry includes a Power-On reset block and a reset input. All devices do not require any programming. Default coefficients and system parameters are stored in internal ROM. The EFF input pin, used to adapt to specific motor and load to improve efficiency, can be used by means of two resistor pairs to choose one of 16 pre-stored load curves in ROM. DIR is a digital input pins which specify the motor direction command (CW or CCW). All devices have an on-chip PLL to generate internal clocks. The PLL requires an external low frequency reference clock (32,768 Hz). The clock can be provided through an RC network connected to CLKIN and XTAL pins. The IRDM982-025MB, IRDM982-035MB integrate high and low side gate drivers for applications up to 500V, it includes integrated Bootstrap FET that emulate bootstrap diode function and six power MOSFETs. The simplified block diagram is shown in Figure 1 in terms of hardware elements. 3 www.irf.com © 2015 International Rectifier April 8, 2015 IRDM982 Series VDD VCC Simplified Block Diagram VSV VSU VSW VBU VBV VBW VBUS 15VDC VSP EFF VSP Dynamic Overcurrent Limit ADC AADV UNDERVOLTAGE & STANDBY VOLTAGE REGULATOR 3.3VDC (Analog) 3.3VDC (Digital) TEMP Internal Temp sensing HIGH VOLTAGE REGISTER FILE HDU U DRIVER (H) ALGORITHM & CONTROL BLOCK PG DIR PSEL U POWER-ON RESET U DRIVER (H) HDV HALL1+ V HALL1OVERCURRENT System Clock (10MHz) HALL2+ CLOCK PRESCALER HDW PRE DRIVERS U DRIVER (H) W HALL2- HALL3+ Clock Synthesis HALL3- DIGITAL (3.3V) ANALOG (3.3V/15V) XTAL/RC Drive HIGH VOLTAGE U DRIVER (L) LDU V DRIVER (L) LDV DCO High Voltage IC W DRIVER (L) LDW VSS COM XTAL CLKIN PLLBYPASS Figure 1 Simplified Block Diagram 4 www.irf.com © 2015 International Rectifier April 8, 2015 IRDM982 Series Qualification Information †† Qualification Level Moisture Sensitivity Level Machine Model ESD Human Body Model Charged Device Model IC Latch-Up Test RoHS Compliant † †† ††† Industrial (per JEDEC JESD 47) Stress Test ; Preconditioning, Temp Cycle, Autoclave, THB, HTSL, LTSL, IOL, ††† MSL3 (per IPC/JEDEC J-STD-020) Floor Life Time ; 168 hours PQFN Conditions ; 1000V Class I, Level A (per JESD78) Testing performed at room temperature ambient.
