Introduction

AI Translation

The INA302 and INA303 (INA30x) devices feature a high common-mode, bidirectional, current-sense amplifier and two high-speed comparators for detecting out-of-range current conditions. The INA302 comparators are configured to detect and respond to overcurrent conditions. The INA303 comparators are configured in a window configuration to respond to overcurrent and undercurrent conditions. These devices use external limit-setting resistors and have an adjustable limit threshold range for each comparator setting. These current shunt monitors can measure differential voltage signals in a common-mode voltage range of –0.1V to 36V independent of the power supply. The open-drain alert outputs can be configured to operate in transparent mode (the output state remains consistent with the input state) or latch mode (the alert output is cleared when the latch is reset). The alert response time of Comparator 1 is less than 1µs, while the alert response time of Comparator 2 is set via an external capacitor and ranges from 2µs to 10s. These devices are powered by a single 2.7V to 5.5V power supply and consume a maximum supply current of 950µA. These devices have an extended rated operating temperature range of -40°C to +125°C and are available in a 14-pin TSSOP package.
