High-Precision Linear Hall-Effect-Based ACS780xLR Current Sensor IC With 200 µΩ Current Conductor SPECIFICATIONS ABSOLUTE MAXIMUM RATINGS Characteristic Symbol Notes Rating Unit
Forward Supply Voltage VCC 6 V Reverse Supply Voltage VRCC –0.5 V Forward Output Voltage VOUT 25 V Reverse Output Voltage VRIOUT –0.5 V Output Source Current IOUT(Source) VOUT to GND 2.8 mA Output Sink Current IOUT(Sink) Minimum pull-up resistor of 500 Ω 10 mA Range K –40 to 125 °C Nominal Operating Ambient Temperature TOP Range L –40 to 150 °C Maximum Junction TJ(max) 165 °C Storage Temperature Tstg –65 to 165 °C
THERMAL CHARACTERISTICS:
May require derating at maximum conditions
Characteristic Symbol Test Conditions [1] Value Unit
Mounted on the Allegro evaluation board ASEK780 85-0807-001 with FR4 substrate and 8 layers of 2 oz. copper (with an area of 1530 mm2 per layer) connected to Package Thermal Resistance RθJA the primary leadframe and with thermal vias connecting 18 °C/W the copper layers. Performance is based on current flow- ing through the primary leadframe and includes the power consumed by the PCB. [1] Additional thermal information available on the Allegro website
TYPICAL OVERCURRENT CAPABILITIES [2][3] Characteristic Symbol Notes Rating Unit
TA = 25°C, 1 s on time, 60 s off time 285 A T Overcurrent I A = 85°C, 1 s on time, 35 s off time 225 A POC TA = 125°C, 1 s on time, 30 s off time 170 A TA = 150°C, 1 s on time, 10 s off time 95 A [2] Test was done with Allegro evaluation board (85-0807-001). The maximum allowed current is limited by TJ(max) only. [3] For more overcurrent profiles, please see FAQ on the Allegro website, www.allegromicro.com.
