Other Parts Discussed in Thread: DRV5053
need a linear Hall device. I chose DRV5056, but the data sheet did not give the power index. I need a low power device. Can I provide the exact power index of DRV5056?

Hello Zhang,
I'm not familiar with the term "power index." However, every TI datasheet specifies the supply current (Icc) of a device. You can multiply this value by your power supply voltage to determine idle power consumption.
For DRV5056, Icc = 6mA. With Vs = 3.3V, P = Icc * Vs = 6mA * 3.3V = 19.8mW.
Our lowest power linear Hall sensor is DRV5053, with Icc = 2.7mA. With Vs = 3.3V, P = 2.7mA * 3.3V = 8.9mW.
