DATASHEET 40A DrMOS Power Module with Integrated Diode Emulation and Thermal Warning Output ISL99140 Features The ISL99140 is a high performance DrMOS power module Compliant with Intel DrMOS rev 4.0 specifications designed for high frequency power conversion. By combining a 40A average output current capability high performance FET driver and MOSFETs in an advanced Supports 3-state 3.3V PWM input package, high density DC/DC converters may be created. Combined with an Intersil PWM controller, a complete voltage Supports 2-state 5V PWM input regulator solution can be created with reduced external Thermal warning output components and minimum overall PCB real estate. Diode emulation option The ISL99140 features a three-state PWM input that, working Adaptive shoot-through protection together with Intersils multiphase PWM controllers, will provide a robust solution in the event of abnormal operating Integrated high-side gate-to-source resistor to prevent self conditions. To further support robust applications, the turn-on due to high input bus dV/dt ISL99140 features a thermal warning output that may be used Undervoltage lockout to notify the power system of an impending thermal fail event. Switching frequencies up to 2MHz The ISL99140 supports high efficiency operation not only at Pb-free (RoHS compliant) heavy loads, but also at light loads via its diode emulation 6x6 QFN package capability. Diode emulation can be disabled for those applications where variable frequency operation is not desired Applications at light loads.
