ZXCT1050 Precision wide input range current monitor

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. Feature.

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.
