36V dual comparator built-in, overcurrent protection, high-speed, high-precision current sense amplifier 'INA302'
The INA302 is a high common-mode bidirectional current sense amplifier equipped with two high-speed comparators, capable of detecting out-of-range current conditions. It detects and responds to overcurrent conditions. Regardless of the supply voltage, it can measure differential voltage signals with a common-mode voltage ranging from -0.1V to 36V. The open-drain alert output can be configured to operate in transparent mode (where the output status follows the input state) or latch mode (where the alert output is cleared when the latch is reset). The alert response time for comparator 1 is less than 1µs, while the alert response for comparator 2 can be set in the range of 2µs to 10s using an external capacitor. It operates with a single supply voltage of 2.7V to 5.5V, with a maximum supply current of 950µA. It functions within an extended operating temperature range of -40°C to +125°C, and the package is a 14-pin TSSOP. *For more details, please contact us.*
