Single-Phase AC Residential Electric Vehicle Charger Reference Design

High-performance energy metering device for single-phase two-wire, single-phase three-wire or anti-tampering active and reactive energy meters. 

A low-power, high-performance ARM Cortex-M0+ based flash microcontroller ideal for a wide range of home automation, consumer, metering, and industrial applications. 

Delivers up to 2.5x throughput improvement and more secure connections vs. Bluetooth 4.1 based products. Developers can easily interface to the device via a standard UART interface, available on most microcontrollers and processors. 

CMOS low-dropout, positive-voltage regulator which can source up to 250mA of current with an extremely low input-output voltage differential of 178mV at 250mA. The low-dropout voltage combined with the low-current consumption of only 1.6µA makes this part ideal for battery operation. 

Dual-op amp with a gain bandwidth product of 14 kHz with a low typical operating current of 600 nA and an offset voltage that is less than 3 mV. Uses Microchip's advanced CMOS technology, which provides low bias current, high-speed operation, high open-loop gain and rail-to-rail output swing. 

Operational Amplifier with a 550 kHz Gain Bandwidth Product (GBWP) and 68° (typ.) phase margin. Operates from a single-supply voltage as low as 1.8V, while drawing 50 µA (typ.) quiescent current. 

Integrated high-side power switch that consists of a TTL compatible input and protected Pchannel MOSFET. It can be used instead of a separate high-side driver and MOSFET in many low-voltage applications. The MIC2514 switches voltage ranging from 3V to 13.5V and delivers more than 400mA continuous current. 

The MIC5209 is an efficient linear voltage regulator with very low dropout voltage, typically 10mV at light loads and less than 500mV at full load, with better than 1% output voltage accuracy.

General-purpose operational amplifier, that operates from 4V to 32V, single or differential (split) supply. The device features a 2.5 MHz unity gain bandwidth, 6V/µs slew rate, and is internally unity-gain compensated. The MIC6211 is available in the tiny, 5-lead SOT-23-5 surface-mount package

Single-voltage supervisor with open-drain reset output that provides accurate power supply monitoring and reset generation in microprocessor based systems. 

Pin-compatible upgrade to the industry standard TC7660 charge pump voltage converter. It converts a +1.5V to +12V input to a corresponding –1.5V to –12V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and EMI.

VXB2 standard crystals are available from 3.5 MHz to 75 MHz in a low-profile 4.2 mm tall metal can package.VXB2 are available in a Fundamental or 3rd overtone mode.
