Bootstrap capacitors are utilized 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 cross-  
conduction prevention. The overvoltage trip point is user adjustable.  
A3940KLP  
(TSSOP with exposed  
thermal pad)  
A3940KLW  
(SOIC)  
The A3940 is supplied in a choice of two power packages, a 28-pin  
TSSOP with an exposed thermal pad (package type LP), and 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).  
Approx. 2X actual size.
