Voltage tolerant termination presence detection
First Claim
1. An apparatus to enable voltage tolerant termination presence detection, comprising:
- sensor circuitry to determine whether a device coupled to the sensor circuitry is to operate in a host mode or a device mode based on a signal on a configuration channel between the device and the sensor circuitry; and
termination circuitry to bias the configuration channel in accordance with the host mode or the device mode based on and after the determination of whether the device is to operate in the host mode or the device mode.

Abstract
Apparatuses and methods associated with voltage tolerant termination presence detection for universal serial bus type-C connectors are disclosed herein. In embodiments, an apparatus to enable voltage tolerant termination presence detection may include sensor circuitry to determine whether a device coupled to the sensor circuitry is to operate in host mode or device mode based on a signal on a configuration channel between the device and the sensor circuitry. In embodiments, the apparatus may further include termination circuitry to bias the configuration channel in accordance with the host mode or the device mode based on the determination of whether the device is to operate in the host mode or the device mode. Other embodiments may be described and/or claimed.

11. A system for termination presence detection, comprising:
-
a die; sensor circuitry, located on the die, to determine whether a device coupled to the sensor circuitry is in a low power condition based on a signal on a configuration channel between the device and the sensor circuitry; and termination circuitry, located on the die, to bias the configuration channel based on the determination of whether the device is in the low power condition, the sensor circuitry to determine whether the device is in the low power condition prior to the configuration channel being biased. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. An apparatus for voltage tolerant termination presence detection, comprising:
-
means for determining whether a device is to operate in a host mode or a device mode based on a voltage present on a configuration channel associated with the device; and means for biasing the configuration channel at a voltage corresponding to either the host mode or the device mode based on the determination of whether the device is to operate in the host mode or the device mode, wherein the means for determining is to determine whether the device is to operate in the host mode or the device mode before the means for biasing biases the configuration channel. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
