As handheld devices become thinner and less expensive, batteries are becoming smaller yet have increased capacity. Highly accurate battery fuel gauges are needed to make efficient use of all available cell energy in today's portable devices.
Maxim MAX1467x Overvoltage Protectors provide protection to circuits against positive faults up to +28VDC. These devices feature a low 65mΩ (typ) and WLP package on-resistance (RON) internal FETs to effectively minimize the voltage drop across the device. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected components. Designers can adjust the overvoltage protection threshold with optional external resistors to any voltage between 5V and 22V. The series also features a reverse bias blocking capability. Unlike other voltage regulators, when the MAX1467x device is disabled, the voltage applied to OUT does not feed back into IN. The over the extended -40°C to +85°C temperature range, makes the Maxim MAX1467x Overvoltage Protectors ideal for tablets, smart phones, E-readers, PC notebooks, and charging USB hosts.
Maxim MAX5813 / MAX5814 / MAX5815 4-channel, low-power, 8- / 10- / 12-bit, voltage-output digital-to-analog converters (DACs) include output buffers and an internal reference that is selectable to be 2.048V, 2.5V, or 4.096V. These Maxim DACs accept a wide supply voltage range of 2.7V to 5.5V with extremely low power (3mW) consumption to accommodate most low-voltage applications. A precision external reference input allows rail-to-rail operation and presents a 100kΩ (typ) load to an external reference. MAX5813 / MAX5814 / MAX5815 have an I²C-compatible, 2-wire interface that operates at clock rates up to 400kHz. The DAC output is buffered and has a low supply current of less than 250µA per channel and a low offset error of ±0.5mV (typical). On power-up, the DAC outputs are reset to zero, providing additional safety for applications that drive valves or other transducers which need to be off on power-up. The internal reference is initially powered down to allow use of an external reference. Theses Maxim devices also allow simultaneous output updates using software LOAD commands or the hardware load DAC logic input (active-low LDAC). MAX5813 / MAX5814 / MAX5815 are ideal for use in a variety of applications, including programmable voltage and current sources, gain and offset adjustment, automatic tuning and optical control, and more.

Maxim MAXREFDES15 Monterey Reference Design delivers an ultra-low power, high accuracy 4-20mA 2-wire current loop sensor evaluation board. The 4-20mA current loop is widely used as an analog communication interface in industrial applications for transmitting the data from remote sensors to a programmable logic controller (PLC) in a central control center over a twisted pair cable. Here, 4mA represents the lowest temperature value, and 20mA represents the highest measured temperature. There are four main advantages of the current loop. First, the accuracy of the signal is not affected by the voltage drop in the loop, as long as the power-supply voltage is greater than the total voltage drop across the loop. Secondly, it uses two wires for power as well as data communication over the entire loop. Thirdly, it is more immune to noise. Lastly, it is offered at a low cost and easy installation.
