The TSC1021AIPT measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage.
The device’s wide input common-mode voltage range, low quiescent current and tiny TSSOP8 packaging enable use in a wide variety of applications (also available in SO8 package).
The input common-mode and power supply voltages are independent. The common-mode voltage can range from 2.8 to 30 V in operating conditions.
The TSC1021AIPT is rugged against abnormal conditions on the input pins: Vp and Vm can withstand up to 60 V in case of voltage spikes, as little as -16 V in case of reversed battery, and up to 4 kV in case of electrostatic discharge.
In addition to the current sensing amplifier, the TSC1021AIPT offers a fully accessible amplifier for output signal conditioning. The device’s overall current consumption is lower than 420 μA.
