High Voltage, Isolated IGBT Gate Driver with Isolated Flyback Controller Data Sheet ADuM4138 and low voltage domains of the chip. Information on the status FEATURES of the chip can be read back from the dedicated outputs. 6 A (typical) peak drive output capability Internal turn off NFET, on resistance: <1 The ADuM4138 includes an isolated flyback controller, Internal turn on PFET, on resistance: <1.2 allowing simple secondary voltage generation. 2 overcurrent protection methods Overcurrent detection is integrated in the ADuM4138 to Desaturation detection protect the IGBT in case of desaturation and/or overcurrent Split emitter overcurrent detection events. The overcurrent detection is coupled with a high speed, Miller clamp output with gate sense input two-level turn off function in case of faults. Isolated fault output The ADuM4138 provides a Miller clamp control signal for a Isolated temperature sensor readback metal-oxide semiconductor field effect transistor (MOSFET) to Propagation delay provide IGBT turn off, with a single rail supply when the Miller Rising: 95 ns typical clamp voltage threshold drops below 2 V (typical) above GND . 2 Falling: 100 ns typical Operation with unipolar secondary supplies is possible with or Minimum pulse width: 74 ns without the Miller clamp operation. Operating junction temperature range: 40C to +150C V and V UVLO DD1 DD2 A low gate voltage detection circuit can trigger a fault if the gate Minimum external tracking (creepage): 8.3 mm (pending) voltage does not rise above the internal threshold within the Safety and regulatory approvals time allowed after turn on (12.8 s typical). The low voltage 5000 V rms for 1 minute per UL 1577 detection circuit detects IGBT device failures that exhibit gate CSA Component Acceptance Notice 5A shorts or other causes of weak drive. DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 Two temperature sensor pins, TS1 and TS2, allow isolated V = 849 V (reinforced/basic) IORM PEAK monitoring of system temperatures at the IGBTs. The secondary Qualified for automotive applications undervoltage lockout (UVLO) is set to 11.2 V (typical) in APPLICATIONS accordance with common IGBT threshold levels. MOSFET and IGBT gate drivers A serial peripheral interface (SPI) bus on the primary side of Photovoltaic (PV) inverters the device provides in field programming of temperature Motor drives sensing diode gains and offsets to the ADuM4138.
