AN-CM-309 Tracking ADC
Renesas Electronics CorporationThis application note describes the implementation of a simple tracking ADC based on digital rheostats of the SLG47004. No external components and no special tuning procedure are required for the proposed ADC structure. Also, the circuit has much better PSRR and temperature drift than a capacitor based counter type ADC. The proposed ADC can be used for monitoring slow-changing signals like temperature, battery voltage, and others.
AN-CM-308 Analog Front End for a Pressure Sensor
Renesas Electronics CorporationThe application note describes the design procedure for Wheatstone bridge sensors. A unique Auto-Trim feature of the SLG47004 is used to achieve the best precision of this analog interface. The application note contains a complete schematic of an analog front-end for a low-cost pressure sensor.
Electric Vehicle (EV) Charger
Renesas Electronics CorporationFueling with electricity offers some advantages that are not available in conventional internal combustion engine vehicles. Because electric motors react quickly, EVs are very responsive and have very good torque. EVs are often more digitally-connected than conventional vehicles, with many EV charging stations providing the option to control charging from a smartphone app. This design approach utilizes an active PFC and asymmetrical full-bridge ZVS converter, along with an RL78/G14 MCU for EV charger applications.
System Benefits:
- Highly integrated MCU
- The ISL6731B provides adaptive control that enables extremely low THD and high PF without DSP
- The RL78/G14 MCU allows users to implement working logic, protections, and features for the driver
- Battery health implementation features
Induction Heating Rice Cooker
Renesas Electronics CorporationThis is a total solution for an induction heating (IH) rice cooker that includes a heating block and human-machine interface (HMI). A highly integrated smart insulated-gate bipolar transistor (IGBT) driver and controller, as well as a low-loss IGBT, help to realize a simple and high-performance IH rice cooker.
System Benefits:
- This total IH solution is made simpler and high-performance with the use of a smart IGBT driver/controller and highly capable 1250V, 25A IGBT.
- HMI and touch key display are supported by a single compact MCU.
- Ultra-low standby power and up to 2.5W output power are provided by a single high-performance buck regulator.
