What are the key features of TSC1031IPT?
- High-side current sensing capability for accurate monitoring on positive supply rails without ground-referenced shunt
- 90 dB minimum common-mode rejection ratio (105 dB typical) for precise differential measurement in noisy environments
- Ultra-low 1100 µV maximum input offset voltage ensuring accurate current measurement across small-value shunt resistors
- 15 µA maximum bias current minimizes measurement error and power loss in the sense resistor path
- Compact SOT-23-8 package suitable for space-constrained power management and battery monitoring designs
What is TSC1031IPT used for?
TSC1031IPT is used in battery management systems and power supply monitors where accurate high-side current sensing on rails up to industrial voltage levels is essential. Its 90 dB CMRR and 1100 µV offset voltage make it well suited for motor drive current feedback loops, telecom rectifiers, and UPS systems that require milliamp-level resolution. The device also fits industrial energy metering and overcurrent protection circuits where the amplifier must reject large common-mode voltages while accurately amplifying small differential shunt voltages.

Frequently Asked Questions
How does the 90 dB common-mode rejection ratio of TSC1031IPT benefit high-side current sensing on noisy 24 V industrial rails?
With a 90 dB minimum CMRR (105 dB typical), TSC1031IPT attenuates common-mode noise on a 24 V rail by a factor of more than 31,000, meaning a 1 V supply noise spike appears as less than 32 µV at the output. This level of rejection allows accurate current measurement with a 10 mΩ shunt resistor producing only millivolt-scale differential signals, making it reliable for overcurrent detection and closed-loop control in 24 V industrial automation systems.
What shunt resistor value is compatible with TSC1031IPT given its 1100 µV input offset voltage specification?
To keep offset-induced current measurement error below 1%, the shunt voltage drop at full-scale current should be at least 110 mV, since the 1100 µV offset represents about 1% of that. For a 5 A full-scale current, this means using a shunt of at least 22 mΩ. At 10 A, a 11 mΩ shunt keeps the offset error under 1%, giving engineers a practical lower bound when selecting shunt values for precision current monitoring with TSC1031IPT.
In which battery management or energy harvesting scenarios is TSC1031IPT preferred over a low-side current sense amplifier?
TSC1031IPT is preferred in battery management systems where the ground reference of the load must not be interrupted for current sensing, such as in Li-ion packs with 3 V to 36 V cell stacks. High-side sensing with TSC1031IPT allows the negative terminal to remain directly connected to system ground, preventing ground-loop interference in multi-cell packs with 8 to 16 series cells. This is critical in automotive 12 V or 48 V battery monitoring and solar MPPT charge controllers where grounding the negative bus to chassis is mandatory.
Does TSC1031IPT fit a compact motor-drive PCB layout, and what footprint does the SOT-23-8 package offer?
Yes, TSC1031IPT in the SOT-23-8 package occupies approximately 2.9 mm × 2.8 mm of PCB area, making it one of the smallest current sense amplifiers available for motor drive current feedback. At a 0.95 mm pitch, the 8 pins still provide adequate signal routing clearance for a 3.3 V logic interface. This footprint is compatible with compact H-bridge and 3-phase inverter boards where sensing current on the high-side bus at up to 10 A is needed without sacrificing board space.
