Description
3940 3940 ADVANCED DATASHEET * 4/9/03 (Subject to change without notice.) H-BRIDGE POWER MOSFET CONTROLLER The A3940 was designed specificall.
Features
* include supply under-voltage and over-voltage, programmable deadtime adjustment for cross-conduction protection, thermal shutdown, and motor lead short-to-supply and short-to-ground protection. The A3940 is available in 28L low profile (1mm) e-TSSOP packaging (LP) which has an exposed pad solderableApplications
* The A3940 provides four high current gate drive outputs capable of driving a wide range of power N-channel MOSFETs. Bootstrap capacitors are utilized to provide the above battery supply voltage required for N-channel FETs. An internal charge pump for the highside will allow for DC (100% duty cycle)3940 Distributors
