EOL Policy

It is an accepted industry practice that occasionally certain devices from a product range will be discontinued. Holtek is no exception to this practice and from time to time after proper reviews and may decide to discontinue certain devices. Reasons for such decisions may be that the devices in question have been superseded by higher performing devices or low consumer demand to mention but a few. As Holtek realizes the discontinuation of devices may create certain difficulties for its customers the following End Of Life or EOL Procedure has been created to inform customers of Holtek's process regarding such devices.
