Texas Instruments INA301A2IDGKR
- Part Number:
- INA301A2IDGKR
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3251543-INA301A2IDGKR
- Description:
- 36V, 550kHz, 4V/μs, high-precision current sense amplifier w/ comparator
- Datasheet:
- ina301
Description
The INA301 includes both a high common-mode current-sensing amplifier as well as a high-speed precision comparator configured to detect overcurrent conditions through measuring the voltage developed across a current-sensing or shunt resistor. This current shunt monitor can measure this differential voltage signal on common-mode voltages that can vary from 0 V up to 36 V, independent of the supply voltage. The device features an adjustable threshold range that is set using a single external limit-setting resistor.
An open-drain alert output on the device can be configured to operate in either a transparent mode where the output status follows the input state or in a latched mode where the alert output is cleared when the latch is reset. The device alert response time is issued in under 1 us to allow for quick detection of overcurrent events.
This device operates from a single 2.7-V to 5.5-V supply, drawing a maximum supply current of 700 μA. The device is specified over the extended operating temperature range (-40°C to 125°C), and is available in an MSOP-8 package.
