概述

Description

INA199B3DCKR is Texas Instruments’ high-side current-sense monitor in an 8-pin VSSOP (DCK) package with Tape & Reel. It measures the voltage across a shunt resistor in the load’s high side and outputs an analog voltage proportional to the load current, serving as a front end for current sensing.
Key points:
- High-side sensing: common-mode up to about 40 V; VCC typically 2.7–5.5 V.
- Output proportional to shunt voltage with a fixed gain; REF pin allows zero-offset adjustment.
- No external ADC required for basic sensing; easy to feed to an ADC or comparator.
- Designed for automotive/industrial use with good precision and fast response.
- Package: 8-pin VSSOP (DCK), RoHS, Tape & Reel.
Typical usage: connect SH+ and SH− across a sense resistor, supply VCC to a logic rail, ground to GND, read VOUT (and adjust with REF if needed). For exact specs and ordering, consult the TI INA199 datasheet.

Features

Concise features of INA199B3DCKR:
- High-side current-sense monitor with current-output architecture
- Wide input/common-mode range: up to about 0–26 V (sensing across a shunt on the high side)
- Differential sense voltage across shunt: typically ±100 mV range
- Supply voltage (Vcc): 2.7 V to 5.5 V (single-supply operation)
- Output: Iout current output; external resistor converts to voltage; Vref pin available for offset/zero set
- Fast response with low offset and good accuracy over temperature
- Wide operating temperature: -40°C to +125°C
- 8-pin package (DCK/RoHS compliant, VSSOP family)
- Suitable for rugged automotive/industrial sensing with simple Iout-to-V conversion
Note: For exact electrical specs (gain, Iout range, input offset, protection features), please consult the TI datasheet for INA199B3DCKR.

Package

The INA199B3DCKR is in an 8-pin DCK package, i.e., VSSOP-8 (Very Small Outline Package) with tape-and-reel.

Pinout

- Pin count: 8 pins (8-pin package, DCKR).
- Function: High-side current-sense amplifier with a current-output (Iout). It senses the voltage across an external shunt resistor (IN+ to IN−) and outputs a current proportional to that differential voltage, with REF for offset. Used for bidirectional current monitoring in the power path.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- Company type: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits; headquartered in Dallas, Texas, and one of the world's largest semiconductor producers.

Application

Typical application areas for INA199B3DCKR:
- High-side current sensing for power supplies and DC-DC converters
- Battery-management and protection in portable and automotive systems
- Overcurrent protection and fault detection in motor drivers and power stages
- Load-current monitoring for regulation and efficiency
- Power-management ICs in automotive, telecom, servers, and consumer electronics
