LATCHUP RECOVERY MECHANISM FOR FINGERPRINT SENSOR BASED ON STATE MONITOR AND HANDSHAKE |
| 摘要 |
Devices and methods are provided for recovering from latchup state in fingerprint sensor devices. For example, a disclosed device can be operated to perform operations that include, receiving, at a microcontroller of the fingerprint sensor device, raw sensor data from a sensor array in communication with the microcontroller, comparing the received raw sensor data against a predetermined threshold, and, based at least partly on the comparing, resetting power supplied to the fingerprint sensor device to recover from a latchup state. |
