ZXCT1050 Precision wide input range current monitor
Description
The ZXCT1050 is a wide input range current monitor, which operates over a range of input
voltages from ground up to VCC-2V. As a result the ZXCT1050 can be used on the high or low side of the load.
The ZXCT1050 provides variable gain by using two external resistors. The first of which sets the transconductance and the second setting the overall gain.
Features
Accurate down to end current sensing
Output
voltage scaling x10
0 to VCC-2V sense input range 2.7 to 20V supply range
50µA quiescent current
SOT23-5 package
Pin connections
The very low offset
voltage enables a typical accuracy of 1% for sense
voltages of only 30mV, giving better tolerances for small sense resistors necessary at higher currents.
Applications
Power supply DC motor and solenoid control Battery management Over current monitor Power management Short circuit detection
Typical application circuit
VCC 1 GND...
