This application note implements a max (or min) voltage finder among several analog inputs. It describes the functional logic, GreenPAK implementation and the obtained results.

This application note explores temperature compensation and calibration for devices such as sensors, thermometers, and more. This note uses the SLG46826 GreenPAK IC to control a digital potentiometer to compensate for the change in the resistance of a thermistor. A digital count is generated that can be read by a processor.

This application note describes how to design and build a fully functional single AA or AAA cell flashlight.

The converter is built on the SLG47513. The IC is a low voltage programmable mixed signal matrix that is designed to be powered from a supply in a range of 1 to 1.65 V, ideal for a single non-rechargeable battery or a NiMH cell. In addition, the SLG47513 contains a huge amount of different macrocells which allows to easy create the circuit up to the task.

This application note describes how to create a portable washing machine using HVPAK. In addition, he device has three timer modes, a constant number of revolutions per minute regardless of the load, and battery discharge notification.

This application note describes how to create an induction heating device using HVPAK.

In addition, the device has four power modes which make it versatile for various tasks, whether it's heating a cup of water or scalding a bolt.

This application note describes the High Voltage GreenPAK IC configured as an integrated smart PWM fan driver.

The design implements fan lock detection without the need for 3-wire fans for temperature proportional speed control.

Cooling fans are widely used and extremely important for electronic devices, especially for those that are constantly running, such as power supplies, servers, computers, and telecommunication equipment.

This application note describes the High Voltage GreenPAK IC design configuration as an integrated smart lock motor driver with dynamic overcurrent detection that accommodates varying supply voltages and loads.

This application note describes several ways of implementing a self-oscillating class D audio power amplifier.

This application note describes the HVPAK configured as a controller for two brushed DC motors with independent control.

This application note illustrates how to use the SLG47004 to implement synchronous detection and lock-in amplification of a sensor signal. The design provides the ability to change the integration time and gain of the lock-in amplifier.

This application note presents a method to use a DC power line for data communication while simultaneously providing power without interruption. This is accomplished via RLC coupling circuits together with GreenPAK IC’s providing modulation (TX) and demodulation (RX).

This application note describes a tamper detector design using the SLG46811 IC as an emulated SPI master to drive the AT45DB161E Flash memory.

This app note implements a SPWM Generator. It describes the implemented logic, GreenPAK implementation detail, and the results obtained.

This application describes how to create a highly reliable, low-power, temperature-stable button function using an SLG47004 and a force-sensitive resistor that can be used for sealed applications.

This application note illustrates how to use the SLG47004 to implement an adjustable analog filter and describes different ways to adjust the filter`s cutoff frequency.

This 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.

The 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.

Fueling 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
