Applications
The TSC2012IDT is used in high-side current monitoring circuits for automotive battery management systems and motor drive power stages where common-mode voltages reach 60V. Its precision bidirectional architecture suits industrial power supply controllers that must measure both charge and discharge current in energy storage systems. The device also appears in server power distribution units and USB power delivery controllers requiring accurate current telemetry across a wide dynamic range.

Frequently Asked Questions
Up to what common-mode voltage can the TSC2012IDT sense current on a high-side shunt resistor?
The TSC2012IDT supports a common-mode input voltage range up to 60V, allowing direct high-side current sensing on 12V, 24V, 36V, and 48V automotive or industrial power rails without requiring a level-shifting network. This 60V rating covers both standard 12V vehicle bus transient spikes and 48V mild-hybrid traction bus operating voltages, making the part suitable for a single design across multiple automotive voltage classes.
How accurately does the TSC2012IDT reject common-mode noise from switching power converters?
The TSC2012IDT achieves a minimum CMRR of 85 dB and a typical CMRR of 120 dB across its full common-mode voltage range. At 120 dB typical rejection, a 1V switching noise transient on the common-mode rail introduces less than 1 µV of equivalent differential error at the amplifier output, preserving current measurement accuracy in buck, boost, and half-bridge converter applications where high-frequency switching noise exceeds 100 kHz.
Can the TSC2012IDT measure regenerative braking current in an EV motor drive system?
Yes. The TSC2012IDT provides bidirectional current sensing, meaning it accurately amplifies both positive (motoring) and negative (regenerative braking) differential voltages across a shunt resistor in a single package. Its 0.6 µA maximum bias current and precision offset trimming maintain measurement linearity from near-zero current during idle phases to full-load regeneration current, without requiring circuit reconfiguration or switching between two unidirectional amplifiers — reducing component count in the motor controller.
What gain options are available on the TSC2012IDT for scaling shunt voltage to an ADC input range?
The TSC2012IDT is available in multiple fixed-gain versions covering gains from 20 V/V to 100 V/V, selectable at order time by MPN suffix. A 50 mΩ shunt carrying 10A produces 500 mV of differential voltage; with a gain of 20 V/V the output reaches 10V, fitting a 10V ADC reference, while a gain of 100 V/V maps the same shunt voltage to a 3.3V microcontroller ADC input with a 1.65V midpoint for bidirectional measurement. No external gain-setting resistors are required, simplifying the layout in the small outline package footprint.
