Description
The AK8781 is an ultra-small latch-type Hall IC that integrates a Hall element and a waveform shaping IC. It is the small latch-type Hall IC in the AKM's small size ever with 60% reduction in package size from the conventional product AK8771. Ultra-small package (0.76mm x 0.76mm x t = 0.38mm) is suitable for rotor position detection of small DC brushless motors. (AKM is the Asahi Kasei Microdevices Corporation)
In addition, it features fast response time and high temperature operation, contributing to microminiaturization and high efficiency of motors.
Key Features
Ultra-small package (0.76mm x 0.76mm x t = 0.38mm) is suitable for rotor position detection of small DC brushless motors.
The AK8781 has fast response capability, so that it can detect high-speed rotation as fast as 95,000r/min *. * Example: rotor poles 4 and phase delay within 5 degree of the electric angle
The operating temperature range of the AK8781 has been expanded from -30°C to 85°C of the AK8771 to -40°C to 125°C. This product can be used safely not only in the industrial machinery field but also in small DCBL motors that do not dissipate heat easily.
Applications
Small DCBL motors
