Microtest 9901 Wireless Charger Auto Test System

The Microtest 9901 Wireless Charger Auto Test System provides comprehensive production-line testing of wireless charging transmitters (Tx) and receivers (Rx) with support for Qi, USB PD2.0, and Qualcomm Quick Charge 3.0 protocols. With up to 44 channels and 150 W power handling, the 9901 tests multiple wireless chargers simultaneously, verifying charging efficiency, protocol negotiation, power delivery accuracy, and critically, Foreign Object Detection (FOD) compliance that ensures charger safety in the presence of metallic objects.

Foreign Object Detection Testing

FOD testing is a mandatory requirement of the Qi specification and a key safety concern: a wireless charger that fails to detect metal objects between the transmitter and receiver can cause dangerous overheating. The 9901 automates FOD test sequences with standardized test objects, measuring detection sensitivity and response time against Qi certification requirements.

Comprehensive Charging Verification

Beyond FOD, the system verifies charging profiles across multiple power levels, measures standby power consumption, and validates thermal derating behavior, providing complete production qualification data. Protocol negotiation testing ensures that chargers correctly handshake with devices across Qi baseline, extended, and proprietary power profiles.

Applications

Wireless charger manufacturers, consumer electronics OEMs, Qi certification test labs, and automotive wireless charging pad producers all deploy the 9901 for production-line validation. As wireless charging adoption accelerates across smartphones, wearables, and automotive applications in India, the 9901 addresses the production test infrastructure that Indian manufacturers need to compete in this growing market.
