3940 General Description
The A3940KLP and A3940KLW are designed especifically for automotive applications which require high-power motors. Each provides four high-current gate drive outputs that are able to drive a wide range of n-channel power MOSFETs in a full bridge configuration. Bootstrap capacitors are used to provide the above-battery supply voltage required for n-channel FETs. An internal charge pump for the high side allows for dc (100% duty cycle) operation of the bridge.Protection features include supply under/overvoltage, thermal shutdown, and motor lead short-to-battery and short-to-ground fault notification, and a programmable dead-time adjustment for crossconduction prevention. The A3940 has two choice of power packages. One is a 28-pin TSSOP with an exposed thermal pad (package type LP), and the other is a 28-pin wide-body SOIC (package type LW). Both package types are available in lead (Pb) free versions, with 100 % matte-tin leadframe plating(suffix T).
It has ten unique festures. The first one is it drives wide range of n-channel MOSFETs. The second one is charge pump to boost gate drive at low-battery-input conditions. The third one is bootstrapped gate drive with charge pump for 100% duty cycle.The forth one is synchronous rectification. The fifth one is fault diagnostic output. The sixth one is adjustable dead-time cross-conduction protection. The seventh one is motor lead short-to-battery and short-to-ground protection. The eigth one is undervoltage/overvoltage protection. The ninth one is -40°C to +150°C, TJ operation. The lasi one is thermal shutdown.
There are also some absolute maximum ratings about it. Load supply voltage range , VBB, VDRAIN , CPI is from -0.6 V to +40 V.Logic input/output voltage range is from -0.3 V to + 6.5 V. Operating temperature range is from -40 to +135 . Junction temperature is +150 . Storage temperature range is from -55 to +150 .
