Product details

Overview

INA207AIDGST 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 - used in telecom power supplies and battery protection circuits.

For engineers reviewing the INA207AIDGST datasheet, INA207AIDGST pinout, INA207AIDGST application, or INA207AIDGST equivalent, this page provides verified functional specifications, SO-14/TSSOP-14 package mapping, comparator timing behavior, gain accuracy over temperature, and design-meaningful alternatives for overcurrent detection systems requiring latch-and-delay response.

Technical Context

The INA207AIDGST integrates a precision current-sense amplifier with fixed 50 V/V gain, two independent comparators sharing internal 0.6-V references (override-capable on pins 3 and 6), and a buffered 1.2-V reference output. Its architecture enables simultaneous analog monitoring and digital fault signaling without external components.

Comparator 1 features active-low reset (pin 8) and latched output (pin 11); Comparator 2 (pins 4, 5, 6, 10) supports user-programmable delay via external capacitor on pin 9, with typical 1.3-µs propagation time and ±2-mV offset. The device maintains 100-dB CMRR over –16 V to 80 V common-mode range and operates across –40°C to 125°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Gain	50 V/V - scales 20–100 mV shunt voltage to 1–5 V output, enabling direct ADC interfacing with 12-bit resolution at 5 V full-scale.
Common-mode input range	–16 V to 80 V - supports high-side sensing in 48-V telecom systems and negative-rail applications like battery discharge monitoring.
Bandwidth	500 kHz - captures fast transient overcurrent events (e.g., short-circuit rise times < 2 µs) without signal distortion.
Quiescent current	1.8 mA - enables always-on monitoring in power-constrained systems such as portable medical devices or IoT edge nodes.
Reference output	1.2 V ±12 mV (±1%) - provides stable bias for external comparators or ADC reference, eliminating need for discrete voltage reference IC.
Comparator 1 response time	1.3 µs - ensures sub-microsecond fault detection for critical overcurrent shutdown in motor drives or DC-DC converters.
Total output error	±3.5% over –40°C to 125°C - guarantees reliable trip-point accuracy in automotive under-hood environments without calibration.

Pinout & Package

INA207AIDGST is packaged in SO-14 (8.65 mm × 3.91 mm) and TSSOP-14 (5.00 mm × 4.40 mm) variants; both share identical pinout and thermal characteristics (R_θJA = 84.9°C/W for SOIC, 112.6°C/W for TSSOP).

Pin/Terminal	Circuit Role	Design Meaning
1 (VS)	Power supply input	Accepts 2.7–18 V; powers all internal blocks including comparators and reference - decoupling capacitor required at pin 1 for stability.
2 (OUT)	Analog output	50× shunt voltage (VIN+ – VIN–); rail-to-rail swing capability enables full dynamic range utilization with 3.3-V or 5-V ADCs.
3 (CMP1 IN– / 0.6V REF)	Comparator 1 negative input / reference tap	Internal 0.6-V reference accessible externally; overriding with external voltage sets custom CMP1 threshold for adaptive overcurrent limits.
4 (CMP1 IN+)	Comparator 1 positive input	Monitors OUT or other analog signal; latched output (pin 11) holds fault state until active-low reset pulse applied to pin 8.
5 (CMP2 IN–)	Comparator 2 negative input	Accepts adjustable threshold (e.g., 0.6 V or external); paired with pin 6 to detect overvoltage/overcurrent with hysteresis.
6 (CMP2 IN+ / 0.6V REF)	Comparator 2 positive input / reference tap	Second 0.6-V reference node; override capability allows independent threshold setting for dual-level fault detection.
7 (GND)	Analog ground	Return path for shunt current and internal circuitry; must be star-connected to minimize noise coupling into sensitive sense inputs.
8 (CMP1 RESET)	Active-low latch reset	Pull low ≥1.5 µs to clear CMP1 OUT (pin 11); open or grounded at power-up ensures defined initial comparator state.
9 (CMP2 DELAY)	Delay capacitor connection	Connects to external capacitor (e.g., 0.1 µF → 0.5 s delay); implements debounced fault response to suppress false triggers from noise spikes.
10 (CMP2 OUT)	Comparator 2 open-drain output	Drives external pull-up; asserts after programmable delay when CMP2 input condition is met - used for timed shutdown or alarm escalation.
11 (CMP1 OUT)	Comparator 1 open-drain output	Latched output remains asserted until reset; directly controls MOSFET gate drivers or microcontroller interrupt lines for immediate action.
12 (1.2V REF OUT)	Reference voltage output	Stable 1.2-V source (±12 mV) with 1-mA load capability; powers external circuitry or serves as precision ADC reference.
13 (VIN–)	Shunt low-side connection	Connects to shunt resistor ground side; high-impedance input minimizes measurement error in low-current applications.
14 (VIN+)	Shunt high-side connection	Handles up to 80 V common-mode; enables high-side sensing in 48-V server PSUs without level-shifting circuitry.

Key Features

Feature	Design Value
Dual comparators with independent thresholds	Enables two-tier fault detection: CMP1 for immediate shutdown (e.g., >120% overload), CMP2 for delayed warning (e.g., >105% sustained for 500 ms).
Programmable delay on CMP2	Capacitor-controlled timing (0.1 µF → 0.5 s) eliminates nuisance tripping from transient surges while preserving response to sustained faults.
1.2-V reference output	Reduces BOM count by replacing external reference ICs; ±100 ppm/°C drift ensures stable thresholds across automotive temperature ranges.
Latching CMP1 with hardware reset	Guarantees fault persistence until explicit system acknowledgment - critical for safety-critical applications like battery management systems.
–16 V to 80 V common-mode range	Supports bidirectional sensing in negative-rail industrial controls and high-voltage telecom rectifiers without auxiliary power rails.
500-kHz bandwidth	Resolves fast current transients (e.g., MOSFET switching edges) with <2 µs settling time, enabling cycle-by-cycle current limiting in SMPS.

FAQ

What is the maximum common-mode voltage supported by the INA207AIDGST?

The INA207AIDGST supports a common-mode input voltage range of –16 V to 80 V. This allows direct high-side sensing in 48-V telecom systems and compatibility with negative-rail applications such as battery discharge monitoring. The specification is guaranteed over the full –40°C to 125°C operating temperature range, and the device maintains 100-dB CMRR across this range.

How does the programmable delay on CMP2 work in the INA207AIDGST?

In the INA207AIDGST, Comparator 2 delay is implemented using an external capacitor connected to pin 9 (CMP2 DELAY). A 0.1-µF capacitor yields a nominal 0.5-second delay; the relationship is linear (t_D = 5 × C_DELAY). This delay applies to both rising and falling edges of CMP2 OUT and prevents false triggering from transient noise while preserving response to sustained overcurrent conditions.

Can the internal 0.6-V reference of the INA207AIDGST be overridden?

Yes - on the 14-pin SO-14 and TSSOP-14 packages of the INA207AIDGST, the internal 0.6-V reference is accessible at pins 3 (CMP1 IN–) and 6 (CMP2 IN+), and can be overridden by external voltage sources. This enables custom threshold programming for both comparators, supporting adaptive overcurrent protection schemes without additional reference ICs.

What is the purpose of the 1.2-V reference output (pin 12) on the INA207AIDGST?

The 1.2-V reference output (pin 12) on the INA207AIDGST provides a precision, low-drift voltage source (±12 mV, ±100 ppm/°C) for external circuitry. It can serve as an ADC reference, bias voltage for op-amps, or threshold for auxiliary comparators - eliminating the need for a discrete reference IC and reducing total system cost and board space.

Does the INA207AIDGST require external components for basic operation?

The INA207AIDGST operates with minimal external components: only a supply decoupling capacitor (0.1 µF) on pin 1 (VS) and pull-up resistors (e.g., 4.7 kΩ) on CMP1 OUT (pin 11) and CMP2 OUT (pin 10) are required for open-drain outputs. No external gain-setting resistors or reference ICs are needed - all key functions (amplifier, dual comparators, 1.2-V/0.6-V references) are fully integrated.
