The HT49R70A-1 is top performer of Holtek's new-generation 8bit general-purpose LCD series 8K OTP microcontroller.
The device possesses an embedded A/D convertor and PWM D/A convertor providing a means to eliminate the usual requirement for externally connected A/D and PWM D/A devices for most battery charging applications.
These internal converters will significantly reduce production costs, simplify overall production, improve reliability, reduce part number stocks and with the benefit of programmability, will provide users with increased application flexibility and reduced delivery times.
In addition and for battery charger applications, the HT46R47's PWM D/A convertor, now running at higher frequencies, permits the use of external inductors with smaller core sizes and lower weights, giving rise to increased efficiencies.
The A/D convertor has four channels with a resolution of 9bit.
And as both channel selection and A/D option selection are under software control, the user is provided with a higher level of flexibility during the application design process.
In addition to battery charger applications, the HT46R47 is suitable for use in switch mode power supplies as well as a range of household appliance applications such as electromagnetic hotplates, electric blankets, electric stoves etc.
