CA-IS23102WH
工程送樣
霍爾效應(yīng)電流傳感器
The CA-IS23101WH current sensor is a cost-effective isolated current sensing solution in the industrial and automotive applications. The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. The current is sensed differentially in order to reject common-mode fields, improving accuracy in magnetically noisy environments. CA-IS23101WH is for 100A~120A and size-limit applications.
The CA-IS23101WH is available in a 10-pin wide-body SOW10 packages. The CA-IS23101WH is rated for operation at working ambient temperatures of -40°C to +125°C.

特性
Differential Hall sensing rejects common-mode fields and nearly zero magnetic hysteresis
Industry-leading noise performance with greatly improved bandwidth for fast control loops or where high-speed current monitored: 400 KHZ bandwidth and 1.2us response time
Two versions respectively support 3.3V & 5V applications
Supports proportional and fixed output modes, and the fixed mode is convenient for customers to ADC differential sample Vref and Vout voltage to reduce external common-mode interference
Supports bidirectional and unidirectional output mode
Support self-test and a variety of diagnostic functions: OVP, OTP, OCD, broken wire, etc
High accuracy
Sensitivity error: ±2.5% from -40°C to 125°C
Non-linearity: ±1% Max
Symmetry: ±1% MaxAdjustable fast overcurrent fault output with 1uS typical response time
