Programmable Linear Hall Effect Sensors with Analog Output

Available in a Miniature Thin Profile Surface Mount Package

Characteristic Definitions

Quiescent Voltage Output In the quiescent state (no significant

magnetic field: B = 0 G), the output, V_OUT(Q), has a constant

ratio to the supply voltage, V_CC, throughout the entire operating

ranges of V_CCand ambient temperature, T_A.

Power-On Time When the supply is ramped to its operating

voltage, the device requires a finite time to power its inter-

nal components before responding to an input magnetic field.

Power-On Time, t_PO, is defined as: the time it takes for the out-

put 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

Guaranteed Quiescent Voltage Output Range The quiescent

voltage output, V_OUT(Q), can be programmed around its nominal

value of 2.5 V, within the guaranteed quiescent voltage range

limits: V_OUT(Q)(min) and V_OUT(Q)(max). The available guaran-

teed programming range for V_OUT(Q)falls within the distributions

of the initial, V_OUT(Q)init, and the maximum programming code

for setting V_OUT(Q), as shown in the following diagram.

Average Quiescent Voltage Output Step Size The average qui-

escent voltage output step size for a single device is determined

using the following calculation:

Delay to Clamp A large magnetic input step may cause the

clamp to overshoot its steady state value. The Delay to Clamp,

t_CLP, is defined as: the time it takes for the output voltage to

settle within ±1% of its steady state value, after initially passing

through its steady state voltage, as shown in the following chart.

Quiescent Voltage Output Programming Resolution The pro-

gramming resolution for any device is half of its programming

step size. Therefore, the typical programming resolution will be:

t₁= time at which output voltage initially

reaches steady state clamp voltage

Err_PGVOUT(Q)(typ)

t₂= time at which output voltage settles to

within 1% of steady state clamp voltage

= 0.5 × Step_VOUT(Q)(typ)

Note: Times apply to both high clamp

(shown) and low clamp.
