TMR angle sensor in a TO-6 package for PCB-less applications
It includes two full TMR bridges, a dedicated ASIC for signal conditioning and integrated passive components (six capacitors and one resistor). The ASIC provides several digital outputs such as Hall emulation (UVW), encoder (ENC), pulse-width modulation (PWM), and SENT on two interfaces simultaneously. Furthermore, its various internal diagnostic features make it suitable for demanding automotive applications where functional safety is required (ASIL B rating). Like all of TDK’s TMR sensors, the TAD2140 features an angle accuracy of ±0.2°, with an angle error of only ±0.05° at room temperature. The sensors are capable of contactless sensing from 0° to 360° over a temperature range of −40°C to +150°C. The sensor’s fast response, high angular accuracy, and advanced compensation algorithms make it suitable for the optimization of motor control applications such as BLDC motor commutation. The sensor can be welded or soldered directly onto a package lead, a connector or a terminal, eliminating the need for a PCB, thus reducing total system size and cost.
