... Continuous-Time Bipolar Switch Family Description The Allegro ® A1201, A1202, A1203, and A1204 Hall-effect bipolar switches are next-generation replacements and extension of the popular Allegro A3134, A3133, and A3132 bipolar switch product line. Overall, the A120x family, produced with BiCMOS technology, consists of continuous-time devices that feature fast power-on time and low-noise operation ...

... A1201, A1202, A1203, and A1204 Bipolar Device Switching The devices of the A120X family provide highly sensitive switching for applications using magnetic fields of alternating polarities, such as ring magnets. There are three switching modes for bipolar devices, referred to as latch, unipolar switch, and negative switch ...

... A1201, A1202, A1203, and A1204 the field is reduced beyond the B level, the device switches OP back to the low state. The typical output behavior of the A120x devices is latching. That is, switching to the low state when the magnetic field at the Hall sensor exceeds the operate point threshold, B point, the output voltage is V ...

... A1201, A1202, A1203, and A1204 The choice between continuous-time and chopper-stabilized designs is solely determined by the application. Battery manage- ment is an example where continuous-time is often required. In these applications chopped with a very small duty cycle CC in order to conserve power (refer to figure 4). The duty cycle ...

... A1201, A1202, A1203, and A1204 Power Derating The device must be operated below the maximum junction temperature of the device Under certain combinations of J(max) peak conditions, reliable operation may require derating sup- plied power or improving the heat dissipation properties of the application. This section presents a procedure for correlating factors affecting operating T ...
