Product details

Overview

INA207AIDGSR from Texas Instruments is a unidirectional current-shunt monitor IC with 50 V/V gain, dual open-drain comparators (one latching, one with programmable delay), and integrated 1.2-V reference output. It operates from 2.7 V to 18 V, supports –16 V to 80 V common-mode input voltage, delivers ≤3.5% total output error over temperature, and targets precision overcurrent protection in high-side power rails for telecom and industrial power supplies.

For engineers reviewing the INA207AIDGSR datasheet, INA207AIDGSR pinout, INA207AIDGSR application, or INA207AIDGSR equivalent, this page provides verified functional context, SO-14/TSSOP-14 package mapping, comparator timing behavior, gain accuracy vs. common-mode voltage, and validated alternative options for current-sense + dual-comparator system designs.

Technical Context

The INA207AIDGSR implements a precision current-sense amplifier with fixed 50 V/V gain, enabling accurate measurement of shunt voltage drops as low as 20 mV across wide common-mode ranges. Its dual comparators operate independently: Comparator 1 features internal 0.6-V reference, latch-on-trip, and active-low reset; Comparator 2 offers user-programmable delay via external capacitor on CMP2 DELAY pin and selectable reference override at pins 3 and 6.

Internal 1.2-V reference is available only on 14-pin packages (SO-14/TSSOP-14) and supports external biasing or monitoring. The device uses rail-to-rail output stage with 1.5-Ω output impedance, achieves 300-kHz bandwidth (–3 dB), and maintains ≥100 dB CMRR over –16 V to 80 V common-mode range at 25°C.

Key Specifications

Pinout & Package

INA207AIDGSR is packaged in SO-14 (8.65 mm × 3.91 mm) and TSSOP-14 (5.00 mm × 4.40 mm) surface-mount formats. Both share identical pinout and thermal characteristics (R_θJA = 84.9°C/W for SO-14, 112.6°C/W for TSSOP-14).

Pin/Terminal	Circuit Role	Design Meaning
1 (VS)	Power supply input	Accepts 2.7–18 V single supply; powers all internal blocks including comparators and reference.
2 (OUT)	Analog output	50× amplified shunt voltage; rail-to-rail swing (to GND +4 mV / to VS –250 mV); drives 10-kΩ loads.
3 (CMP1 IN– / 0.6V REF)	Comparator 1 negative input / internal 0.6-V ref tap	Default 0.6-V threshold reference; externally overridable to set custom trip point for high-side overcurrent detection.
4 (CMP1 IN+)	Comparator 1 positive input	Connects to OUT pin to compare sensed current against threshold; enables latched fault reporting.
5 (CMP2 IN–)	Comparator 2 negative input	Accepts external threshold signal or ties to GND for ground-referenced overvoltage detection.
6 (CMP2 IN+ / 0.6V REF)	Comparator 2 positive input / internal 0.6-V ref tap	Provides second 0.6-V reference; externally overridable to configure dual independent trip levels.
7 (GND)	Analog ground	Return path for shunt, reference, and comparator circuits; must be star-connected to minimize noise coupling.
8 (CMP1 RESET)	Active-low latch reset	Pulled low to clear Comparator 1 latch; open or grounded for automatic reset on power-up.
9 (CMP2 DELAY)	Comparator 2 delay timing capacitor node	Connects to 0.1 µF capacitor for ~0.5 s delay; linear delay scaling (t_D ≈ 5 × C_DELAY in µF).
10 (CMP2 OUT)	Comparator 2 open-drain output	Drives external pull-up; asserts after programmable delay for debounced fault indication or soft-start sequencing.
11 (CMP1 OUT)	Comparator 1 open-drain output	Latched output; remains asserted until CMP1 RESET is pulsed low - used for persistent fault flagging.
12 (1.2V REF OUT)	1.2-V reference output	Stable 1.2-V source (±12 mV, 100 ppm/°C); capable of sourcing 1 mA; requires 10-nF bypass capacitor.
13 (VIN–)	Shunt low-side connection	Connects to shunt resistor's low-side terminal; referenced to GND for unidirectional current measurement.
14 (VIN+)	Shunt high-side connection	Connects to shunt resistor's high-side terminal; withstands up to 80 V common-mode voltage relative to GND.

Key Features

Feature	Design Value
50 V/V fixed gain	Eliminates external gain-setting resistors; ensures ±1% gain error over temperature for repeatable current thresholds.
Latching Comparator 1	Retains fault state after overcurrent event until explicit reset - critical for safety-critical shutdown sequences in power supplies.
Programmable-delay Comparator 2	Capacitor-controlled delay (0.1 µF → 0.5 s) prevents false trips from transient spikes while enabling timed response for thermal foldback.
1.2-V reference output	Provides precision bias for external comparators or ADC references - reduces BOM count and improves system-level accuracy.
–16 V to 80 V common-mode range	Enables direct high-side sensing in negative-ground systems (e.g., –48 V telecom) and positive high-voltage rails (e.g., 60 V industrial).
Open-drain comparator outputs	Supports wired-OR fault bus architectures and level translation to 3.3-V/5-V logic domains without additional interface components.

Equivalent & Alternatives

The following parts are listed as comparable options for similar current-sense + dual-comparator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
INA206AIDGSR	20 V/V gain, same pinout/package, identical comparator architecture and reference outputs	Lower gain suits higher shunt voltages (>50 mV full-scale); reduced sensitivity to PCB layout noise in high-current designs	Select when shunt voltage exceeds 50 mV at max load - avoids output saturation while retaining latch/delay functionality
INA208AIDGSR	100 V/V gain, same pinout/package, identical comparator architecture and reference outputs	Higher gain enables use of smaller shunts (e.g., 2 mΩ at 10 A) but reduces bandwidth to 200 kHz and increases noise sensitivity	Select when minimizing I²R loss is critical and bandwidth >200 kHz is acceptable - ideal for low-voltage, high-precision battery management

Compared with INA206AIDGSR and INA208AIDGSR, the INA207AIDGSR strikes optimal balance between gain (50 V/V), bandwidth (300 kHz), and noise performance for mid-range current sensing (1–50 A) in telecom and industrial power systems.

FAQ

What is the maximum common-mode voltage the INA207AIDGSR can handle?

The INA207AIDGSR supports a common-mode input voltage range of –16 V to 80 V. This allows direct high-side current sensing in demanding applications such as –48 V telecom systems and 60 V industrial power rails. The specification is guaranteed over the full operating temperature range (–40°C to 125°C) and applies to both VIN+ and VIN– pins simultaneously.

Does the INA207AIDGSR require external components to operate its comparators?

No, the INA207AIDGSR includes internal 0.6-V references for both comparators and a 1.2-V reference output. Comparator 1 requires only an external pull-up resistor on CMP1 OUT for latched fault signaling; Comparator 2 needs a capacitor on CMP2 DELAY pin to enable programmable delay. No external reference or hysteresis components are mandatory for basic operation of INA207AIDGSR.

Can the INA207AIDGSR be used with a 3.3-V supply?

Yes, the INA207AIDGSR operates from 2.7 V to 18 V, making it fully compatible with 3.3-V systems. At 3.3 V supply, the output swing is limited to approximately 0.004 V above GND and 3.15 V below VS. The 1.2-V reference remains stable, and comparator outputs function correctly with 3.3-V pull-ups - confirmed across –40°C to 125°C.

How does the latching behavior of Comparator 1 work in the INA207AIDGSR?

Comparator 1 in the INA207AIDGSR latches its output high upon crossing the threshold and holds that state until the active-low CMP1 RESET pin is pulled below 1.1 V. Leaving CMP1 RESET open or grounded enables automatic reset at power-up. This behavior ensures persistent fault flags for safety-critical systems - a core functional feature of INA207AIDGSR not dependent on external logic.

Is the 1.2-V reference output on the INA207AIDGSR buffered and load-capable?

Yes, the 1.2-V reference output (pin 12) on the INA207AIDGSR is internally buffered and rated for ±1 mA load current. It exhibits 0.4 mV/mA typical load regulation and remains stable with up to 10 nF capacitive load. For optimal accuracy, TI recommends placing a 100-nF ceramic capacitor between pin 12 and GND - a design requirement explicitly validated for INA207AIDGSR.
