The A1210LUA-T is a continuous-time Hall-effect latch in a 3-pin SIP through-hole package, designed for automotive and industrial motor commutation applications. It operates from 3.8 V to 24 V with a ±30 V absolute maximum supply voltage rating and supports ambient temperatures from -40°C to 150°C. The device features reverse-battery protection, integrated voltage regulation, and a 25 mA sink current capability, with no external bypass capacitor required. It is AEC-Q100 automotive qualified, includes factory-programmed switch points for accuracy, and has a magnetic switch point range of -150 G to 150 G. The UA package is the matrix HD style, recommended for new designs. The output is an open-drain NMOS transistor.
The A121x family provides reliable and efficient latching functionality for a variety of applications. These continuous-time devices offer fast power-on time, low-noise operation, and integrated protection features. Factory programming ensures accurate switchpoint thresholds.
