ACS709
High Bandwidth, Fast Fault Response Current Sensor IC
In Thermally Enhanced Package
Description (continued)
the open drain Overcurrent Fault pin will transition to a logic low
state. Factory programming of the linear Hall sensor IC inside of
the ACS709 results in exceptional accuracy in both analog and
digital output signals.
The internal resistance of the copper path used for current sensing is
typically 1.1 m Ω , for low power loss. Also, the current conduction
path is electrically isolated from the low voltage device inputs and
Selection Guide
outputs. This allows the ACS709 family of sensor ICs to be used
in applications requiring electrical isolation, without the use of
opto-isolators or other costly isolation techniques.
Applications include:
? Motor control and protection
? Load management and overcurrent detection
? Power conversion and battery monitoring / UPS systems
