INA169NA/3K TI/Texas Instruments SOT23-5 Semiconductor Power Management Chip (PMIC)

INA169NA/3K is a high-voltage side current sensing amplifier produced by Texas Instruments (TI), packaged in SOT-23-5. It is mainly used to accurately measure the voltage on the shunt resistor and monitor the current. You can visit TI's official website or distributor page to check detailed information, such as Mouser product page or Lichuang Mall. ‌‌‌

What can this chip mainly do

Core function: Designed specifically for high side current measurement, it converts the differential voltage on the shunt resistor into current output, and then converts it into voltage through an external resistor for ADC reading.

Typical applications: Widely used for current monitoring in automobiles, telephones, computers, battery systems, chargers, and power management devices.

Gain setting: The gain is determined by the external load resistance and can be set to any gain of 1 to 100 or more, with high flexibility. ‌‌‌

What are the key technical parameters

Power supply and common mode voltage: Supports a wide range of 2.7V to 60V, independent of the input common mode voltage.

Bandwidth: The gain bandwidth product is 440kHz, suitable for mid to low frequency current detection.

Static current: The typical value is only 60 µ A, with low power consumption.

Accuracy and Temperature: The accuracy is about 0.5%, and the industrial grade working temperature range is -40 ° C to 85 ° C (some parameters display up to 125 ° C, please refer to the data manual for details).

Packaging form: SOT-23-5 surface mount packaging, compact in size. ‌‌‌
