Characteristic Definitions
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, tPO, 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, VCC(min), as shown in the
following chart.
Delay to Clamp
A large magnetic input step may cause the
clamp to overshoot its steady state value. The Delay to Clamp,
tCLP, 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
In the quiescent state (no significant
magnetic field: B = 0 G), the output, VOUT(Q), has a constant
ratio to the supply voltage, VCC, throughout the entire operating
ranges of VCC and ambient temperature, TA.
Guaranteed Quiescent Voltage Output Range
The quiescent
voltage output, VOUT(Q), can be programmed around its nominal
value of 2.5 V, within the guaranteed quiescent voltage range
limits: VOUT(Q)(min) and VOUT(Q)(max). The available guaran-
teed programming range for VOUT(Q) falls within the distributions
of the initial, VOUT(Q)init, and the maximum programming code
for setting VOUT(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:
V
OUT(Q)maxcode –VOUT(Q)init
2n–1
Step
VOUT(Q) =
.
(1)
where:
n is the number of available programming bits in the trim
range,
2n–1 is the value of the maximum programming code in the
range, and
VOUT(Q)maxcode is the quiescent voltage output at code 2
n–1.
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:
Err
PGVOUT(Q)(typ)
= 0.5 × StepVOUT(Q)(typ)
.
