Allegro MicroSystems, LLC Announces New 0° To 360° Angle Sensor ICs
2017-02-28 | ReturnThe A1337 and A1338 devices were designed with safety-critical application requirements in mind. They include user-controlled, on-chip logic built-in self-test (L-BIST) and full signal path
diagnostics to enable customers to determine if the IC is operating properly. Both devices support a Low RPM mode for slower rate applications and a High RPM mode for high-speed applications. High RPM mode is for applications that require higher refresh rates to minimize error due to latency. Low RPM mode is for applications that require higher resolution operating at lower angular velocities.
The A1337 device also includes integrated Turns Counter and Low-Power Mode functions. The Low-Power Mode enables the device to be connected directly to the vehicle battery and minimizes power consumption when the vehicle is in the key-off state. The Turns Counter function allows the device to keep track of either 45° or 180° turns of the motor when the part is in Low-Power Mode, allowing it to keep track of the motor position even when the vehicle is in the key-off state.
The A1337 and A1338 devices are available in two package options, a single-die, 14-pin TSSOP and a dual-die, 24-pin TSSOP. Both packages are lead (Pb) free with 100% matte-tin leadframe plating.
