Allegro MicroSystems Europe adds AEC-Q100-qualified Hall-effect latch ICs
Allegro MicroSystems Europe announces a low voltage family of AEC-Q100 qualified three-wire Hall-effect latches. The APS12205, APS12215, and APS12235 are produced on the Allegro advanced BiCMOS wafer fabrication process, which implements a patented high-frequency chopper stabilisation technique. This technique achieves magnetic stability over the full operating temperature range, says Allegro, and eliminates offsets inherent in devices with a single Hall element that are exposed to harsh application environments.
This APS122x5 family of devices is designed for systems where the sensor ICs will be behind a voltage regulator or that do not require double battery or reverse battery protection.
The APS122x5 family is optimised for the speed and position sensing of ring-magnets (motors/encoders) or other moving/rotating assemblies and is targeted at 2.8 to 5.5V automotive and industrial markets. They can be used in applications such as motor commutation and speed and direction sensing in automotive window lifts, sunroofs and tail-/lift-gates, white goods, automated window blinds, garage door openers and sliding doors.
The APS12205, APS12215, and APS12235 have the same package, pinout, and magnetic characteristics as the industry-standard A1220, A1221, and A1223, respectively. They are qualified to the same standards, says Allegro, and can operate at temperatures up to 175 degree C.
All three family members are offered in two package styles. The LH is a SOT-23 W style, miniature, low-profile package for surface-mount applications. The UA is a three-pin, mini, single inline package (SIP) for through-hole mounting. Both packages are lead (Pb) free, with 100% matt-tin leadframe plating.
The APS12205, APS12215, and APS12235 Hall-effect switches are available with a choice of magnetic switch-points and package. The APS122x5 family of devices complements Allegro’s industry standard A122x family by offering 3.3/5V specific devices.
Allegro MicroSystems develops, manufactures and markets semiconductors and serves high-growth applications within the automotive market, as well as focusing on office automation, industrial, and consumer/communications solutions. It has design, applications, and sales support centres located worldwide.
