ACS709

High Bandwidth, Fast Fault Response Current Sensor IC

In Thermally Enhanced Package

Features and Benefits

Description

▪ Industry-leading noise performance with 120 kHz

bandwidth through proprietary amplifier and filter

design techniques

TheAllegro^™ACS709currentsensorICprovideseconomical

andprecisemeansforcurrentsensingapplicationsinindustrial,

automotive, commercial, and communications systems. The

device is offered in a small footprint surface mount package

that allows easy implementation in customer applications.

▪ Integrated shield greatly reduces capacitive coupling

from current conductor to die due to high dV/dt, and

prevents offset drift in high-side applications

▪ Small footprint surface mount QSOP24 package

▪ 2100 VRMS isolation voltage between primary current

path and sensor IC electronics

▪ 1.1 mΩ primary conductor resistance for low power loss

▪ User-settable Overcurrent Fault level

▪ Overcurrent Fault signal typically responds to an

overcurrent condition in < 2 μs

TheACS709consistsofaprecisionlinearHallsensorintegrated

circuit with a copper conduction path located near the surface

of the silicon die. Applied current flows through the copper

conduction path, and the analog output voltage from the Hall

sensor IC linearly tracks the magnetic field generated by the

applied current. The accuracy of the ACS709 is maximized

with this patented packaging configuration because the Hall

element is situated in extremely close proximity to the current

to be measured.

▪ Filter pin capacitor sets analog signal bandwidth

▪ ±2% typical output error

▪ 3 to 5.5 V, single supply operation

▪ Factory trimmed sensitivity, quiescent output voltage,

and associated temperature coefficients

▪ Chopper stabilization results in extremely stable

quiescent output voltage

▪ Ratiometric output from supply voltage

High level immunity to current conductor dV/dt and stray

electric fields, offered byAllegro proprietary integrated shield

technology, guarantees low output ripple and low offset drift

in high-side applications.

The voltage on the Overcurrent Input (VOC pin) allows

customers to define an overcurrent fault threshold for the

device.Whenthecurrentflowingthroughthecopperconduction

path (between the IP+ and IP– pins) exceeds this threshold,
