DC1851A: Demo Board for the LTC2872 RS232/RS485 Dual Multiprotocol Transceiver with Integrated Termination.

Demonstration circuit 943 is a complete power controller for a USB power device. It features the LTC6047 and provides a full-featured 1.25A linear lithium-ion CC/CV battery charger with timer termination and 4.2V charge voltage, a USB power manager, and a PowerPath manager for the battery. The USB input voltage range is 4.35V to 5.5V and the wall adapter input is 4.35V to 6V. It also features a programmable 1.5A input current limit that can be set at 500mA or 100mA for USB applications. The wall adapter input has overvoltage protection up to 13V. An external MOSFET disconnects the wall adapter when the voltage exceeds 6V.

Demo board DC2783A features the LT3040, a 200mA high performance, robust voltage reference/DAC buffer. LT3040 has ultralow output noise, ultrahigh power supply rejection ratio (PSRR) and low dropout voltage for powering noise sensitive, high accuracy systems. DC2783A has two inputs: V+ and VIN. V+ supplies power to the buffer, operating over a range from 2V to 20V. VIN is the regulation set-point for the output with a range from 0V to 15V. Current limit is programmable by connecting a resistor, R3, from ILIM to GND. The ILIM can also serve as a current monitor pin with a range from 0V to 300mV. LT3040 has fast start capability. Connecting FS pin across an input low pass filter resistor, R2, fast starts the LT3040. Fast start circuitry is typically triggered active if VFS − VIN ≥ 100mV and stays active until VFS – VIN ≤ 7mV. If fast start functionality is not needed, connect FS to VIN by setting R2 to 0Ω and applying the input voltage at FS. LT3040 has a fault flag to indicate faults at the output. Built-in protection includes reverse battery protection, reverse current protection, internal current limit with foldback and thermal limit with hysteresis. The LT3040 datasheet gives a complete description of the part, operation and applications information. The datasheet must be read in conjunction with this Demo Manual for demonstration circuit DC2783A. The LT3040 is assembled in a 12-lead MSOP and a 10-lead (3mm x 3mm) plastic DFN package with an exposed pad on the bottom-side of the IC. Proper board layout is essential for maximum thermal performance.

Demonstration circuit 1697A features the LTC2945. The LTC2945 is a rail-to-rail system monitor that measures current, voltage, and power. It features an operating range of 2.7V to 80V and includes a shunt regulator for supplies above 80V to allow flexibility in the selection of input supply. The current common mode measurement range of 0V to 80V is independent of the input supply. An onboard 0.75% accurate 12-bit ADC measures load current, input voltage and an auxiliary external voltage. A 24-bit power value is generated by digitally multiplying the measured 12-bit load current and input voltage data. Minimum and maximum values are stored and an overrange alert with programmable thresholds minimizes the need for software polling. Data is reported via a standard I2C interface. The demo board is populated for a 5A application. This can be changed by populating R1 accordingly.
