This application note video shows the rechargeable toy car with push-to-start/hold-to-stop functionality. The device is created using the HVPAK SLG47105. The following design provides constant voltage on the motor, regardless of the battery charge and "push-to-start / hold-to-stop" capability. Thanks to the hold-to-stop functionality, the car automatically turns off when it's stuck. So, if the child directs it somewhere and forgets about the toy, the car will switch off and will not consume more power, thus saving the battery. The CC-CV battery charger control is also implemented.
