ADuM4135

Data Sheet Single-/Dual-Supply, High Voltage Isolated IGBT Gate Driver with Miller Clamp ADuM4135 FEATURES GENERAL DESCRIPTION 4 A peak drive output capability Output power device resistance: <1 Ω Desaturation protection Isolated desaturation fault reporting Soft shutdown on fault Miller clamp output with gate sense input Isolated fault and ready functions Low propagation delay: 55 ns typical Minimum pulse width: 50 ns The ADuM4135 is a single-channel gate driver specifically optimized for driving insulated gate bipolar transistors (IGBTs). Analog Devices, Inc., iCoupler® technology provides isolation between the input signal and the output gate drive. The ADuM4135 includes a Miller clamp to provide robust IGBT turn-off with a single-rail supply when the gate voltage drops below 2 V. Operation with unipolar or bipolar secondary supplies is possible, with or without the Miller clamp operation. Operating temperature range: −40°C to +125°C The Analog Devices chip scale transformers also provide Output voltage range to 30 V isolated communication of control information between the Input voltage range from 2.3 V to 6 V high voltage and low voltage domains of the chip. Information Output and input undervoltage lockout (UVLO) on the status of the chip can be read back from dedicated Creepage distance: 7.8 mm minimum outputs. Control of resetting the device after a fault on the 100 kV/µs common-mode transient immunity (CMTI) 20 year lifetime for 600 V rms or 1092 V dc...
