Abstract
Haptic power control techniques provide improved power control for the haptic generator to reduce deficiencies of operation and/or increase performance of the haptic generator across various thermal conditions. In some examples, a first resistance measurement can be obtained and used for estimating an actuation voltage limit for the haptic generator. In some examples, estimating the actuation voltage limit for the haptic generator using the first resistance measurement includes estimating a first actuation voltage limit for the haptic generator when the first resistance measurement is a first resistance value and estimating a second actuation voltage limit for the haptic generator when the first resistance measurement is a second resistance value.
