Introduction There are many off-the-shelf ICs available for charging Li-Ion batteries. In this Note we present a Li-Ion charger design based on a GreenPAK mixed-signal IC and a GreenFET load switch from Dialog Semiconductor. There are some advantages in using the GreenPAK approach. For one, we may integrate the solution with…

Want to make a flashlight by yourself? This step by step guide aims to outline how to design and build a fully functional single AA or AAA cell flashlight. …

Introduction The main goal of this application is to design an Induction Heater device using the SLG47105V. The system is designed using the HVPAK macrocells and other internal and external components within the HVPAK to drive two powerful N-MOSFETs to control the Induction Heater. The proposed Induction Heater has four power…

Introduction This application note describes three PWM design variants using GreenPAK IC: 1. “0–100% PWM” is PWM signal generator with the possibility to control the signal’s duty cycle from 0 to 100% full range, controlled by external or internal signal (for instance: signal from external pin, I2C signal, from a comparator…

Introduction Some applications require oscillators not already served by the on-chip oscillators inside a GreenPAK IC. This application note describes two designs wherein a few passive external components can be used as an oscillator, which is connected to a GreenPAK. The first design is a low-power RC oscillator. The second is…

Introduction In this application note, a pair of Renesas GreenPAK™ SLG46537’s is used to create the electronic components for a simple basketball arcade machine. These machines tally baskets scored within a certain amount of time. They can often be found in arcades like Chuck E. Cheese’s or Dave & Buster’s. Basketball…

Introduction Analog 4–20 mA current loops are one of the most used communication buses in industrial environments, where environmental variables, process sensing, and control is required. This bus type is named after its maximum and minimum current values across the line; 4 mA and 20 mA. Current loops are used not…

Introduction This application note describes the HV PAK configuration for LED control. Since LEDs have high efficiency and brightness, this makes them leaders in many lighting applications. In this case, the SLG47105 is configured as the LED driver with four buttons to control LED brightness and color temperature. …

Introduction Brushless DC electric motors (BLDC), also known as electronically commutated motors (ECMs, EC motors) or synchronous DC motors, are synchronous motors powered by DC electricity via an inverter or switching power supply, which produces an AC electric current to drive each phase of the motor via a closed loop controller…
