Introduction On our last blog post, we talked about motor surge protection in battery powered systems. One of the suggested methods was adding a Negative Temperature Coefficient (NTC) thermistor, but we didn’t explain how to choose an NTC for a project that includes miniature motors.
Many haptic applications, in particular, wearables, face severe trade-offs in overcoming limitations in power supplies. A battery’s volume is directly related to a host of other desirable specifications, such as voltage, current, or capacity. For many designers, squeezing as much life out of their battery
