Description

The Allegro® A1205 Hall-effect bipolar switch is a next generation replacement and extension of the popular Allegro A3134 bipolar switch. The A1205 has identical specifications as the A1201 but is recommended for applications that require pulsing VCC to conserve power. For standard applications, where VCC is constant, please refer to the A1201 through A1204 devices.
