7 V to 60 V • Independent Supply and Input Common-Mode Voltages • Single Resistor Gain Set • Low Quiescent Current (60 μA Typical) • Wide Temperature Range: –40°C to +125°C • Package: TSSOP-8 2 Applications • Electric Power Steering (EPS) Systems • Body Control Modules • Brake Systems • Electronic Stability Control (ESC) Systems 3 Description The INA139-Q1 and INA169-Q1 (INA1x9-Q1) are high-side, unidirectional, current shunt monitors.
Wide input common-mode voltage range, high-speed, low quiescent current, and TSSOP-8 packaging enable use in a variety of applications.
The device converts a differential input voltage to a current output.
This current is converted back to a voltage with an external load resistor that sets any gain from 1 to over 100.
Although designed for current shunt measurement, the circuit invites creative applications in measurement and level shifting.
Both the INA139-Q1 and INA169-Q1 are available in a TSSOP-8 package, and are specified for the –40°C to +125°C temperature range.
