P9261-0NLG28

Power Management - Specialized Overview

The P9261-0NLG28 is a highly integrated wireless power transmitter controller supporting WPC Qi specifications. It features an embedded 32-bit ARM Cortex-M0 processor for programmability and low standby power. The device supports multiple coils in full-bridge or half-bridge configurations, generating power through the coil to detect receivers and adjust voltage based on feedback. It enables 15W output with bidirectional communication or 5W for standard receivers. Integrated drivers control external FETs, while a step-down regulator increases efficiency. Protection includes over-current, over-voltage, and over-temperature safeguards.
