Key Features
- High-voltage high-side operation tolerates common-mode input voltages well above 5 V rail, enabling current sensing on bus voltages up to 60 V
- Precision gain accuracy with low offset error delivers accurate current measurement across shunt resistor values from milliohms to ohms
- Tiny 5-pin SOT-23 package occupies minimal board area for space-constrained motor drive and battery management designs
- Single-function architecture with rail-to-rail output allows direct connection to ADC inputs referenced to ground
- RoHS-compliant e3 finish in tape-and-reel packaging supports high-volume automated PCB assembly
Applications
The LTC6101HVACS5#TRMPBF monitors load current on high-side rails in battery-powered industrial systems and portable equipment where the sense resistor sits above a 12 V, 24 V, or 48 V bus. It is used in DC motor drive overload protection circuits and power supply output current limiting, where its high common-mode range eliminates the need for an isolated measurement path. Automotive body-control modules and EV auxiliary power converters also employ it to feed high-side current readings into low-voltage ADC channels without additional level shifting.

Frequently Asked Questions
What common-mode input voltage range can the LTC6101HVACS5#TRMPBF handle for high-side current sensing?
The LTC6101HVACS5#TRMPBF is rated for high-voltage high-side operation and tolerates common-mode input voltages up to 60 V, far beyond the 5 V or 3.3 V supply of the downstream microcontroller. This wide range allows current monitoring on 12 V, 24 V, and 48 V bus rails in industrial power systems and automotive applications without requiring isolation or a separate floating supply.
How does the LTC6101HVACS5#TRMPBF output connect to a microcontroller ADC for current measurement?
The LTC6101HVACS5#TRMPBF produces a rail-to-rail output voltage referenced to ground, so it connects directly to a standard 0 V to 5 V or 0 V to 3.3 V ADC input pin on a microcontroller without a level shifter. The output voltage is proportional to the current through the external shunt resistor, and the gain is set by a resistor ratio, enabling the designer to scale the full-scale current range to match the ADC's input span and achieve 12-bit or better resolution.
What shunt resistor value is recommended when using LTC6101HVACS5#TRMPBF for motor current sensing at 24 V?
For 24 V motor current sensing, a shunt resistor in the range of 5 milliohms to 50 milliohms is typical, with the gain-setting resistors chosen so that the maximum motor current produces a full-scale output near 5 V or 3.3 V. A 10 milliohm shunt at 10 A generates a 100 mV differential input, and a gain of 33 V/V produces a 3.3 V output, keeping power dissipation in the shunt below 1 W while providing sufficient signal swing for 10-bit ADC resolution.
For a compact motor-control PCB, how small is the LTC6101HVACS5#TRMPBF footprint compared to alternatives in larger packages?
The LTC6101HVACS5#TRMPBF is housed in a 5-pin SOT-23 package with a body size of approximately 2.9 mm × 1.6 mm, which is roughly 4 times smaller than an 8-lead SOIC alternative. This compact footprint allows the current sense function to be placed adjacent to the shunt resistor and half-bridge MOSFET with minimal routing distance, reducing parasitic inductance in the sense path and improving measurement accuracy in high-frequency switching applications above 100 kHz.
