Vue d'ensemble

Description

INA180B1IDBVR is a Texas Instruments high-side current-sense monitor (INA180 family). It measures the voltage across a shunt resistor in the load/current path and provides a voltage output proportional to the sensed current, enabling real-time monitoring and control in power, automotive, and protection circuits. The B1 and IDBVR suffixes indicate a specific fixed-gain grade and the 8‑pin VSSOP package variant, respectively. Typical use cases include motor drives, buck/boost converters, battery management, and protection schemes. For exact electrical characteristics (gain, common-mode range, input offset, output swing, and supply range), see the INA180B1IDBVR datasheet.

Features

INA180B1IDBVR features (concise):
- High-side current-sense amplifier with current-output (Iout) for easy external conversion to voltage
- Wide input common-mode range (senses across shunt up to high side, typically up to ~26 V)
- Single-supply operation (roughly 2.7 V to 5.5 V)
- Shunt-sense voltage range suitable for small mV drops (low offset, high accuracy)
- External resistor converts Iout to a measurable voltage; no internal gain-setting resistor needed
- Low offset and drift with good CMRR for accurate current measurement
- Fast response and suitable bandwidth for dynamic current sensing
- Temperature range suitable for industrial/ automotive use (typical -40°C to +125°C)
- RoHS-compliant packaging suitable for compact designs
Notes: The device uses a current-output topology and is designed for high-side current sensing with simple interfacing to ADCs via an external resistor.

Package

The INA180B1IDBVR comes in the DBV package — an 8‑pin Small Outline Package (SOP‑8), RoHS‑compliant.

Pinout

pin count: 8 pins (VSSOP-8 package, IDBVR).
function: High-side current-sense monitor. It senses the voltage across a shunt resistor on the high-side and outputs a voltage proportional to the sensed current (with a reference pin available for offsetting). Typical pins include SH+, SH-, VCC, GND, OUT, REF, and an enable/diagnostic option depending on the variant.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is a global American semiconductor company that designs and manufactures analog and embedded processing integrated circuits (ICs).

Application

INA180B1IDBVR is a high-side current-sense amplifier ideal for monitoring current with a shunt resistor in noisy, high-voltage rails. Key applications: automotive powertrains and battery management; load current monitoring for DC-DC converters; motor control and drives; power supplies and adapters; solar/inverter and energy-storage systems; telecom/server power rails; protection/current‑limit schemes in UPS and industrial equipment.

Equivalent

TI equivalents (same device family, same footprint): INA180A1IDBVR and INA180C1IDBVR. These are other grade variants of the INA180 in the IDBVR package with the same pinout. For non-TI cross-references, consult Analog Devices' AD8210/AD8213 families and verify that gain, common-mode range, and output format meet your design.
