Datasheet Summary
A1444 and A1445
Low-Voltage Full-Bridge Brushless DC Motor Driver with Hall mutation, Externally Controlled Speed Regulation, Soft Switching, and Reverse Battery, Short Circuit, and Thermal Shutdown Protection
Features and Benefits
- Low voltage operation: 1.8 to 4.2 V
- Externally controlled motor speed regulation
- Fast motor startup and braking function allows faster start-stop cycles
- Reverse voltage protection on the VDD and S¯¯L¯¯E¯¯E¯¯P pins
- Output short circuit and thermal shutdown protection
- Soft switching algorithm for reduced audible switching noise and EMI interference
- Unidirectional operating mode results in motor rotation in only one direction
- Chopper...
