Product details

Overview

INA206AIPWR from Texas Instruments is a unidirectional current-shunt monitor IC with 20 V/V gain, dual open-drain comparators (CMP1 latched, CMP2 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 500-kHz bandwidth, and is housed in a TSSOP-14 package. It is used for overcurrent protection and supply monitoring in telecom power supplies and battery management systems.

For engineers reviewing the INA206AIPWR datasheet, INA206AIPWR pinout, INA206AIPWR application, or INA206AIPWR equivalent, this page provides verified functional specifications, validated pin functions for the TSSOP-14 variant, confirmed comparator timing behavior, and real-world design values for current-sense accuracy, reference stability, and latch/reset operation - all specific to the INA206AIPWR device.

Technical Context

The INA206AIPWR integrates a precision current-sense amplifier with fixed 20 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 shunt voltage measurement and dual-threshold event detection without external references.

Comparator 1 features active-low reset (pin 8) and latching output (pin 11); Comparator 2 (pins 4, 5, 6, 10) supports user-programmable delay via external capacitor on pin 9. The 14-pin TSSOP package uniquely exposes both 1.2-V REF OUT (pin 12) and dual 0.6-V reference override inputs - functionality absent in the 10-pin VSSOP variant.

Pin/Terminal	Circuit Role	Design Meaning
1 (VS)	Power supply input	Accepts 2.7–18 V; powers all internal blocks including comparators and reference; requires local 0.1-µF bypass.
2 (OUT)	Analog output	Voltage output = 20 × (VIN+ − VIN−); rail-to-rail swing (Vs − 0.25 V to GND + 4 mV) enables full dynamic range use.
3 (CMP1 IN− / 0.6V REF)	Comparator 1 negative input / reference override	Internal 0.6-V reference node; externally overridable to set custom CMP1 threshold; high-impedance (10 kΩ).
4 (CMP1 IN+)	Comparator 1 positive input	Compares against pin 3; latched output on pin 11 remains asserted until active-low reset pulse on pin 8.
5 (CMP2 IN−)	Comparator 2 negative input	Fixed 0.6-V reference input; not override-capable; used for standard overcurrent trip detection.
6 (CMP2 IN+ / 0.6V REF)	Comparator 2 positive input / reference override	Internal 0.6-V reference node; externally overridable to adjust CMP2 threshold independently of CMP1.
7 (GND)	Analog ground	Return path for shunt current, amplifier, and comparators; must be star-connected to minimize noise coupling.
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 state.
9 (CMP2 DELAY)	Comparator 2 delay capacitor connection	Connects to external capacitor (e.g., 0.1 µF → 0.5 s delay); controls both rising/falling edge response of CMP2 OUT.
10 (CMP2 OUT)	Comparator 2 open-drain output	Drives external pull-up; asserts low on overcurrent; delay applies to both assertion and release transitions.
11 (CMP1 OUT)	Comparator 1 open-drain output	Latched output; stays low after trip until pin 8 receives reset pulse; used for persistent fault signaling.
12 (1.2V REF OUT)	Reference voltage output	Stable 1.2-V source (±12 mV, ≤100 ppm/°C); supplies external circuits or calibrates auxiliary comparators.
13 (VIN−)	Shunt low-side connection	Connects directly to shunt resistor low terminal; designed for Kelvin sensing to reject trace resistance errors.
14 (VIN+)	Shunt high-side connection	Accepts up to 80 V common-mode; enables high-side current sensing in positive- or negative-ground systems.

Key Features

Feature	Design Value
Dual independent comparators	CMP1 provides latched fault flag with hardware reset; CMP2 offers programmable delay for debounced overcurrent detection - eliminating need for external timers or microcontroller polling.
Integrated 1.2-V reference	Low-drift (≤100 ppm/°C), load-regulated (0.4 mV/mA) output on pin 12 - eliminates external reference IC in space-constrained designs like server VRMs.
Override-capable comparator references	Pins 3 and 6 accept external voltages to replace internal 0.6-V references - enabling flexible trip-point configuration for multi-level fault grading (e.g., warning vs. shutdown).
High common-mode rejection	100 dB min (–40°C to 125°C) - rejects noise from switching regulators and motor drivers, ensuring accurate current measurement in noisy industrial environments.
Wide supply and temperature range	Operates from 2.7 V to 18 V supply and –40°C to 125°C ambient - suitable for automotive body control modules and outdoor telecom equipment.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
INA207AIPWR	50 V/V gain (vs. 20 V/V); identical pinout, reference, and comparator architecture.	Better suited for lower shunt voltages (e.g., 20 mV full-scale) where higher gain improves SNR; requires recalibration of comparator thresholds.	Select when sensing smaller shunt drops (<50 mV) and system layout allows gain-dependent threshold adjustment.
INA219AIDR	I²C digital output (vs. analog); integrated 12-bit ADC, no dual comparators or reference output.	Requires microcontroller host; lacks hardware latch/delay; supports bidirectional sensing but no 1.2-V REF for external circuits.	Choose for systems needing digital telemetry and software-configurable alerts, where analog autonomy and reference sourcing are not required.

Compared with INA207AIPWR and INA219AIDR, the INA206AIPWR provides optimal analog signal chain simplicity for fixed-gain, latch-based overcurrent protection with self-contained reference - making it ideal for standalone protection circuits without MCU dependency.

FAQ

What is the maximum common-mode voltage the INA206AIPWR can handle?

The INA206AIPWR supports a common-mode input voltage range of –16 V to 80 V. This allows high-side sensing in 48-V telecom systems and compatibility with negative-rail configurations. Absolute maximum ratings specify –18 V to 80 V differential, but operational specification is –16 V to 80 V per datasheet Section 7.3. The INA206AIPWR maintains accuracy and functionality across this full range when powered within its 2.7–18 V supply window.

Does the INA206AIPWR provide a usable reference voltage output?

Yes, the INA206AIPWR provides a buffered 1.2-V reference output on pin 12 (1.2V REF OUT). It is specified at 1.188 V to 1.212 V (±1%), with drift ≤100 ppm/°C and load regulation of 0.4 mV/mA (sourcing up to 1 mA). This output is exclusive to the 14-pin SOIC and TSSOP packages - not available on the 10-pin VSSOP variant - and is intended for biasing external comparators or ADC references.

How does the latch function work on the INA206AIPWR's Comparator 1?

Comparator 1 in the INA206AIPWR features a latched output (pin 11) that remains asserted after a trip condition until explicitly reset. Reset is performed by applying an active-low pulse (≥1.5 µs wide) to pin 8 (CMP1 RESET). Leaving pin 8 open or grounded at power-up initializes CMP1 OUT in a known low state. This latch mechanism enables persistent fault signaling without continuous microcontroller supervision - a key feature for safety-critical overcurrent protection in the INA206AIPWR.

Can the comparator reference voltages be modified on the INA206AIPWR?

Yes, on the 14-pin TSSOP package (INA206AIPWR), pins 3 (CMP1 IN− / 0.6V REF) and 6 (CMP2 IN+ / 0.6V REF) allow external override of the internal 0.6-V comparator references. Applying an external voltage to either pin replaces the internal reference for that comparator, enabling custom trip thresholds. This capability is documented in Section 6 (Pin Functions) and Section 8.3.3 of the SBOS360F datasheet and is unique to the 14-pin variants of the INA206AIPWR.

What is the purpose of the CMP2 DELAY pin (pin 9) on the INA206AIPWR?

The CMP2 DELAY pin (pin 9) on the INA206AIPWR connects to an external capacitor to program a user-defined delay for Comparator 2 output transitions. For example, a 0.1-µF capacitor yields ~0.5 s delay (per Equation 1 in Section 8.3.4). This delay applies to both rising and falling edges of CMP2 OUT (pin 10), providing hardware-based debouncing for noisy signals - eliminating software filtering or external RC timers in applications like power supply soft-start monitoring or inrush current suppression.
