The TPS22910A, TPS22912C, and TPS22913B/C are small, low rON load switches with controlled turn on. The device contains a P-channel MOSFET that can operate over an input voltage range of 1.4 V to 5.5 V. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage GPIO control signals.

The TPS22910A, TPS22912C, and TPS22913B/C devices provide reverse current protection in ON and OFF states. An internal reverse voltage comparator disables the power-switch when the output voltage (VOUT) is driven higher than the input voltage (VIN), by VRCP, to quickly (10 µs typ) stop the flow of current towards the input side of the switch. Reverse current protection is always active, even when the power-switch is disabled. Additionally, under-voltage lockout (UVLO) protection turns the switch off if the input voltage is too low.

The TPS22913B/C contains a 150-Ω on-chip load resistor for quick output discharge when the switch is turned off.

This family of devices have various slew rate options to avoid inrush current (see for details), are available in an ultra-small, space-saving 4-pin WCSP packages, and are characterized for operation over the free-air temperature range of –40°C to 85°C.

TIDA-01589 — 具備雜訊消除與回波抵銷功能的高保真、近場雙向音訊參考設計

人機互動需要聲學介面,以提供全雙工免手持通訊。在免手持模式下,來自喇叭的部分遠端或近端音訊訊號會耦合至麥克風。此外,在雜訊環境中,除了可擷取有用的近端音訊訊號外,麥克風還會擷取環境雜訊。擷取的多麥克風音訊訊號會受到聲學背景雜訊及回波訊號破壞,這些訊號會大幅降低所需訊號的清晰度,並限制後續音訊處理系統的性能。此參考設計展示了雙麥克風,其用於透過立體聲 ADC 實現音訊輸入,透過低功耗 DSP 執行雜訊降低、聲音回波消除和其他音訊品質強化演算法。此設計還採用了 TI 智慧型放大器技術,可透過微型喇叭實現高品質、高 SPL 音訊輸出。
