The MAXREFDES1153 is a monitoring solution for genuine lithium-ion (Li+) battery packs with 2 to 15 cells connected in series. This reference design provides an accurate state of charge (SOC) in milliamp-hours (mAh) or percentage (%), as well as precision measurements of current, voltage, and temperature for multicell battery packs.
This TI reference design is for an automotive high-side dimmable taillight that uses a BCM to provide the taillight. In this TI reference design, the high-side driver TPS1H100-Q1 is used to output PWM power with different duty cycles. Linear LED drivers TPS92630-Q1 and TPS92638-Q1 are used to drive LEDs with constant current.
12-bit, 4-20mA loop-powered thermocouple measurement system using ARM Cortex-M3
KITFS85FRDMEVM is a development board for the 24V truck market. It is used to maintain Vbat current up to 60V and can support all transient pulses.
This LED driver reference design drives a 700mA constant current to a single string of LEDs with forward voltages up to 60V. The design allows PWM dimming based on supply chopping. The input power supply is chopped on and off at 300Hz to 1kHz frequency to achieve LED brightness control. The driver uses a fixed-frequency boost converter, controlled by the MAX16834 LED driver. This unique reference design limits the input inrush current to negligible levels without compromising either the input or output filtering. Design schematics and test results are provided.
This TI verified design implements a 16-bit differential 4-channel multiplexed data acquisition system at 400 KSPS throughput for high voltage differential inputs for ±20 V (40 Vpk-pk) industrial applications. The circuit is implemented with a 16-bit successive approximation register (SAR) analog-to-digital converter (ADC), a precision high-voltage signal conditioning front end, and a 4-channel differential multiplexer (MUX). This design details the use of the OPA192 and OPA140 to optimize a precision high-voltage front-end driver circuit to achieve the excellent dynamic performance of the ADS8864 .
This reference design is a complete application design for an automotive LED application. It utilizes the MAX15005 current-mode controller to boost a standard lead-acid car battery to 21V for driving a string of automotive LEDs.
Analog input and output modules are standard components of programmable logic controllers (PLCs) or distributed control systems (DCS). In these modules, the increasing number of channels per module and the thinner and thinner modules present design challenges for isolated power supplies. All designers facing these challenges will benefit from the TIDA-00237 as its total design size is less than 2.54x2.54mm and its height is less than 5mm. It uses a flyback approach, which means no optocoupler feedback is required, and has a wide input voltage range of 12V-36V. This design provides +/-15V and 5V isolated low-noise outputs, making it ideal for driving data converters or analog front ends.
The PCM1864 circular microphone board (CMB) is a low-cost easy-to-use reference design for applications that require clear-spoken audio, such as voice triggering and speech recognition. This TI Design uses a microphone array to capture a voice signal, and converts it to a digital stream that can be used by DSP systems to extract clear audio from noisy environments.
Pasadena (MAXREFDES31#) is a highly efficient, flyback, 3.3V and 5V Class 4 powered device (PD) with a 40V to 57V auxiliary input. The design features the MAX5969B as the controller. The MAX5974A controls current-mode PWM converters and provides frequency foldback for both the auxiliary input and power-over-Ethernet (PoE) applications. The design is a high-performance, compact, IEEE® 802.3af/at compliant, cost-efficient solution for a PD with power level up to Class 4. The design can also support the auxiliary-input to provide approximately 21W output power.

Simple easy to use high side current sense amps protects power supplies as a result of irregular supply voltage caused by short-circuit conditions.
This reference design implements a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors. The UCC23513 gate driver used is available in a 6-pin wide body package and LED light analog input, and can be used as a pin-for-pin replacement for existing optically isolated gate drivers. This design shows that the UCC23513 input stage can be driven using all existing configurations for driving optoisolated gate drivers. In-phase shunt resistor based motor current sensing is implemented using the AMC1300B isolated amplifier and DC link voltage, and IGBT module temperature sensing is implemented using the AMC1311 isolated amplifier. This design uses the C2000™ LaunchPad™ to control the inverter.
