ACS758xCB
Thermally Enhanced, Fully Integrated, Hall Effect-Based
Linear Current Sensor IC with 100 μ Ω Current Conductor
Definitions of Dynamic Response Characteristics
Power-On Time (t PO ). When the supply is ramped to its operat-
ing voltage, the device requires a finite time to power its internal
components before responding to an input magnetic field.
Power-On Time, t PO , is defined as the time it takes for the output
voltage to settle within ±10% of its steady state value under an
applied magnetic field, after the power supply has reached its
minimum specified operating voltage, V CC (min), as shown in the
chart at right.
Increasing V IOUT (V)
Rise time (t r ). The time interval between a) when the device
reaches 10% of its full scale value, and b) when it reaches 90%
of its full scale value. The rise time to a step response is used to
derive the bandwidth of the device, in which ?(–3 dB) = 0.35 / t r .
Both t r and t RESPONSE are detrimentally affected by eddy current
losses observed in the conductive IC ground plane.

Propagation delay (t PROP ). The time required for the device
output to reflect a change in the primary current signal. Propaga-
tion delay is attributed to inductive loading within the linear IC
package, as well as in the inductive loop formed by the primary
conductor geometry. Propagation delay can be considered as a
