概述

Description

INA199C1DCKR is Texas Instruments’ single-channel high-side current-sense monitor in an 8-pin DCKR package. It measures the small voltage drop across a low-value shunt resistor placed in series with the load and converts that into a current at the Iout pin. An external resistor on Iout converts this current to a voltage that can be read by a microcontroller or ADC, enabling simple current monitoring. The device is designed for high-side sensing with a wide common‑mode input range, making it suitable for power-management, battery monitoring, load current sensing, and basic current‑limit protection circuits. The C1DCKR suffix denotes the specific package/temperature variant of the part. For exact electrical characteristics (sense range, Iout sensitivity, supply range, and any built‑in comparator/threshold features), refer to the TI datasheet for INA199C1DCKR.

Features

Here are the key features of the INA199C1DCKR:
- High-side current-sense monitor with current-output (Iout) proportional to shunt current
- Wide common-mode voltage range up to 26 V for high-side sensing
- Single-supply operation: 2.7 V to 5.5 V
- REF pin to offset the output; external resistor converts Iout to a usable voltage for ADCs
- Bidirectional current sensing (positive/negative depending on shunt polarity)
- Low input offset and high accuracy
- 8-pin package (DCKR), RoHS-compliant; suitable for industrial temp range
- Tape-and-reel variant available (DCKR) for automated assembly
These features enable accurate, low-cost current monitoring in high-side applications with minimal external components.

Package

An 8-pin VSSOP (Very-Small-Outline) package, DCKR variant.

Pinout

- Pin count: 8 pins (8-pin package, e.g., VSSOP-8 in DCKR variant).
- Function: High-side current-sense monitor/amp. It measures the voltage drop across a shunt resistor and provides an analog output voltage proportional to the sensed current (unidirectional current sensing).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (ICs), embedded processors, sensors, and related electronics components.

Application

- High-side current sensing for power rails (DC-DC converters, battery packs)
- Battery management and protection circuits
- Overcurrent protection and fault detection in automotive, industrial, and consumer electronics
- Motor control and drive current measurement
- Energy monitoring, power meters, solar inverters, UPS systems
- Load current profiling and monitoring in embedded systems

Equivalent

Exact pin-for-pin equivalents do not exist outside TI. Closest TI drop-ins: another INA199 variant (e.g., INA199A1) in a different package/revision. Other TI options with similar function: INA213/INA214 (different gain/config) and INA226 (digital I2C/SPI output). Across vendors, viable equivalents include Analog Devices AD8210/AD8211 and Linear Technology LTC6102, but pinouts and interfaces differ and PCB/layout changes are likely required. Check accuracy, gain, supply range, and packaging when selecting a substitute.
