Product details
Overview
INA207AIDGSRG4 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, and delivers 500-kHz bandwidth for real-time shunt current sensing in high-side or low-side configurations. It is used in overcurrent protection circuits for telecom power supplies.
For engineers reviewing the INA207AIDGSRG4 datasheet, INA207AIDGSRG4 pinout, INA207AIDGSRG4 application, or INA207AIDGSRG4 equivalent, key selection criteria include its 50 V/V fixed gain accuracy (±1% max gain error), latch/reset control on CMP1, user-adjustable delay on CMP2 via external capacitor, 1.2-V reference output capability, and SO-14/TSSOP-14 package compatibility with industrial temperature range (–40°C to 125°C).
Technical Context
The INA207AIDGSRG4 integrates a precision current-sense amplifier with two independent comparators sharing internal 0.6-V references-both overrideable on pins 3 and 6 in 14-pin packages. Comparator 1 features active-low asynchronous reset (CMP1 RESET) and latched output behavior, while Comparator 2 supports programmable delay via external capacitor on CMP2 DELAY (pin 9), enabling adjustable response timing for transient suppression.
Its current-sense path provides 50 V/V gain with ±2.2% total output error over temperature, 80 dB minimum CMRR at –16 V to 80 V common-mode range, and 1.5 Ω output impedance. The 1.2-V REF OUT (pin 12) delivers up to 1 mA load current with ±12 mV tolerance and ≤100 ppm/°C drift, supporting auxiliary biasing or comparator threshold referencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 50 V/V - scales 20–100 mV shunt voltage to 1–5 V output for ADC interfacing or comparator thresholds |
| Common-Mode Input Range | –16 V to 80 V - enables direct high-side sensing in 48-V telecom or 12-V automotive systems without level-shifting |
| Bandwidth | 500 kHz - supports fast transient detection in battery charger or welding equipment current loops |
| Quiescent Current | 1.8–2.2 mA - enables low-power operation in always-on monitoring applications |
| Reference Output | 1.2 V ±12 mV - provides stable bias for external circuitry or comparator reference override |
| Comparator Delay Range | 0.5 s with 0.1 µF capacitor - configurable overcurrent hold-off time prevents nuisance tripping |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial embedded environments |
Pinout & Package
INA207AIDGSRG4 is packaged in a 14-pin TSSOP (PW) with body size 5.00 mm × 4.40 mm and standard SOIC-compatible footprint. Pinout is identical to SO-14 variant and validated per TI SBOS360F Rev F.
| 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) | Current-sense amplifier output | High-impedance voltage output scaled by 50× shunt voltage; drives 10-kΩ loads with <2.2% error |
| 3 (CMP1 IN– / 0.6V REF) | Comparator 1 negative input / internal ref tap | Default 0.6-V reference; externally overridable to set custom trip point for high-accuracy fault detection |
| 4 (CMP1 IN+) | Comparator 1 positive input | Monitors OUT or external signal; latches on overthreshold until CMP1 RESET is pulsed low |
| 5 (CMP2 IN–) | Comparator 2 negative input | Accepts shunt voltage, reference, or system signal; paired with pin 6 for differential threshold setting |
| 6 (CMP2 IN+ / 0.6V REF) | Comparator 2 positive input / internal ref tap | Default 0.6-V reference; externally overridable to configure asymmetric or adaptive thresholds |
| 7 (GND) | Analog ground | Return path for shunt, amplifier, and comparator circuits; must be star-connected to minimize noise coupling |
| 8 (CMP1 RESET) | Active-low asynchronous reset | Pulled low to clear CMP1 OUT latch; open or grounded for automatic power-up reset behavior |
| 9 (CMP2 DELAY) | Capacitor connection for delay timing | Connects to external capacitor (e.g., 0.1 µF = 0.5 s delay); sets hold-off time before CMP2 OUT asserts |
| 10 (CMP2 OUT) | Open-drain comparator 2 output | Drives external pull-up; asserts low after programmed delay when CMP2 IN+ exceeds CMP2 IN– |
| 11 (CMP1 OUT) | Open-drain comparator 1 output | Drives external pull-up; latched low until CMP1 RESET is asserted; indicates persistent overcurrent condition |
| 12 (1.2V REF OUT) | 1.2-V reference output | Stable 1.2-V source with ±12 mV tolerance; supplies bias for external comparators or ADC references |
| 13 (VIN–) | Shunt low-side connection | Connects to shunt resistor ground side; enables low-side current sensing with full common-mode rejection |
| 14 (VIN+) | Shunt high-side connection | Connects to shunt resistor load side; supports high-side sensing up to +80 V common-mode voltage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-sense monitor with dual comparators applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA207AIDR | Same 50 V/V gain, SO-14 package; no G4 suffix - RoHS-compliant but not automotive-grade (AEC-Q100 not certified) | Lacks AEC-Q100 qualification; unsuitable for automotive under-hood use where INA207AIDGSRG4 is required | Select INA207AIDGSRG4 for automotive safety-critical designs; choose INA207AIDR for cost-sensitive industrial PCBs without qualification needs |
| INA214AIDGSR | Lower 20 V/V gain; no CMP2 DELAY pin; no 1.2-V REF OUT; same SO-14/TSSOP-14 footprint | Supports only basic overcurrent detection without programmable delay or auxiliary reference - insufficient for telecom hold-off requirements | Use INA207AIDGSRG4 when dual-comparator flexibility, delay programming, or 1.2-V reference are mandatory; INA214AIDGSR fits simpler single-threshold designs |
Compared with INA207AIDR and INA214AIDGSR, the INA207AIDGSRG4 uniquely combines AEC-Q100 qualification, 50 V/V gain optimized for mid-range shunt voltages, CMP2 programmable delay for transient immunity, and 1.2-V REF OUT for system-level biasing - making it the only choice for automotive and telecom applications requiring all four features simultaneously.

FAQ
What is the maximum common-mode voltage supported by the INA207AIDGSRG4?
The INA207AIDGSRG4 supports a common-mode input voltage range from –16 V to +80 V on VIN+ and VIN– pins. This allows direct high-side current sensing in 48-V telecom systems and low-side sensing in negative-rail industrial applications without external level-shifting circuitry. The specification is guaranteed over the full –40°C to 125°C operating temperature range per SBOS360F Rev F.
Does the INA207AIDGSRG4 provide a usable reference voltage output?
Yes, the INA207AIDGSRG4 provides a 1.2-V reference output on pin 12 (1.2V REF OUT), specified as 1.188 V to 1.212 V at 25°C with ≤100 ppm/°C drift over –40°C to 85°C. It can source up to 1 mA and is intended for biasing external comparators or ADC references. Unlike the 0.6-V internal references on pins 3 and 6, the 1.2-V output is accessible only on 14-pin packages like the INA207AIDGSRG4.
How is the programmable delay on Comparator 2 implemented in the INA207AIDGSRG4?
The INA207AIDGSRG4 implements Comparator 2 delay using an external capacitor connected to pin 9 (CMP2 DELAY). The delay time tD in seconds equals 5 × CDELAY in microfarads - e.g., a 0.1-µF capacitor yields 0.5 s delay. This RC-based timing controls both rising and falling edges of CMP2 OUT and is exclusive to 14-pin versions. The internal current source charges the capacitor to a 0.6-V threshold to trigger output assertion.
What is the function of the CMP1 RESET pin on the INA207AIDGSRG4?
The CMP1 RESET pin (pin 8) is an active-low asynchronous input that clears the latched state of Comparator 1 output (CMP1 OUT). When pulled low, it forces CMP1 OUT high regardless of input conditions. If left open or grounded, the INA207AIDGSRG4 powers up in reset state. Leaving it unconnected results in transparent comparator operation; asserting it low is required to release a latched overcurrent fault condition.
Is the INA207AIDGSRG4 qualified for automotive applications?
Yes, the INA207AIDGSRG4 carries the G4 suffix indicating AEC-Q100 Grade 1 qualification (–40°C to +125°C ambient), making it suitable for automotive under-hood and battery management applications. Its SO-14/TSSOP-14 packaging, 1.8–2.2 mA quiescent current, and 50 V/V gain stability over temperature meet stringent automotive reliability and performance requirements defined in the TI INA20x product folder.
