Description
3625 AND 3626 POWERHALL® SENSOR/DRIVERS FOR BRUSHLESS DC MOTORS Requiring a minimum of external components, the UDN3625M and UDN3626M are monolithic .
Features
* s 900 mA /12 V or 400 mA /24 V Operation s Speed-Control (PWM) Capability s Locked-Rotor Indication s Minimum External Components s Over-Current Protected s Thermal Protection s Enhanced Reliability s Reduced Cost
Output current rating will be limited by ambient temperature, supply voltage, and dut
Applications
* Integrated into the ICs are a highsensitivity Hall-effect sensor, control and commutating logic, a stable voltage regulator, extensive self and system protective functions, and two high-current saturated npn outputs. Both ICs include thermal shutdown, output over-current limiting, and output transi
