DRV5056: drv5056 power consumption?

Part Number: DRV5056
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.
