Part Details for CSD25402Q3A . by Texas Instruments

This advanced motor implements closed-loop speed control to maintain an exact RPM across the load torque profile.  The magnetic rotor position is sensed by the DRV5013 Hall-effect sensors, and the DRV8308 controller decides when to drive the CSD88537

This reference design showcases an Infrared LED illumination sub-system for Internet Protocol (IP) network cameras with day and night vision. The system features a cut filter control: LED dimming: ambient light measuring and ballasting for current of each IR LED string. Ballasting is an alternative for driving multi-string LED arrays with a single string LED driver while maintaining uniform illumination under low-light conditions. The OPT3001 Ambient Light Sensor (ALS) with precise visible light measuring and good IR rejection: is an ideal preferred replacement for photodiodes: photoresistors or other ambient light sensors.

This reference design includes a complete power management solution for a standalone emergency call (eCall) system in an automotive environment. The circuit is supplied directly from the car battery rail. It also manages a backup battery to power the eCall system while the car battery rail is not available. It includes power path management which routes the available power rail directly to four DC/DC converters which are supplying the required functional blocks of the eCall system. The solution is optimized to operate at maximum efficiency while powered from the backup battery.

The PMP40069 is a reference design for portable DLP pico projectors  It also has a 3 cell battery charger.  The battery will provide the power to the projector when the adapter isn't available . The solution implements  DLPA3000 PMIC/LED driver: DLPC3438 display controller and SMBus battery buck-boost charge controller BQ25700A. The DLPA3000 PMIC is a fully integrated dedicated PMIC/LED driver providing all system analog power requirements and can drive 0~6 amp RGB LEDs. The buck-boost charger is compatible with 5/9/12/15/20V output adapters. The charger has high efficiency and provides 3A charge current to a 3 cell battery.

This converter is used for Class 1 PoE PD applications where isolation is not required.  The TPS2378 PD controller plus LM5006 buck converter provide 5V/560mA with good efficieny in a small size.  The LM5006 can be configured with a diode rectifier for lowest cost or a synchronous FET r

PMP10594 is a synchronous 4-switch buck-boost converter reference design which utilizes the LM5175 controller for battery charger applications. The output voltage set point can be adjusted by a PWM signal over the range of 7.1V to 9.2V. I2C programming allows independent control of the average input current and charge current. Full scale input current limiting is 6A: while charge current is programmable to 12.5A. The LM5175 average current loop sets a maximum output current of 20A: which should never engage under normal circumstances. Additional pulse-by-pulse current limiting is inherent in the current-mode controller: making this a very robust design. A battery disconnect switch is used to provide trickle charging if the battery voltage is less than 6V.

TIDA-00179 is an EMC-compliant universal digital interface to connect to absolute position encoders like EnDat 2.2: BiSS®: SSI or HIPERFACE DSL®. This reference design supports a wide-input voltage range from 15 V to 60 V (24-V nom). A connector with 3.3-V logic I/O signals allows for direct interface to the host processor like Sitara AM437x or Delfino F28379 to run the corresponding master protocol.Master implementations are available on Sitara AM437x (EnDat2.2: BiSS and HIPERFACE DSL) or Delfino DesignDRIVE (EnDat2.2 and BiSS). This design allows the host processor to select between a 4-wire encoder interface like EnDat 2.2 and BiSS or a 2-wire interface with power over RS-485 like HIPERFACE DSL. To meet the selected encoder's supply range: the design offers a programmable output voltage with either 5.25 V or 11 V. The design's power supply offers protection against over-voltage and short circuit according to the selected encoder's voltage range to prevent damage during a cable short. TIDA-00179 has been tested up to 100-m cable length with EnDat 2.2 and 2-wire HIPERFACE DSL encoders.
