The MIC2776 is a power supply supervisor which provides under-voltage monitoring and power-on reset generation in a compact 5-pin SOT package. Features include an adjustable under-voltage detector, a delay-generator, a manual reset input, and a choice of active-high, active-low, or open-drain active-low reset output. The user-adjustable monitoring input is compared against a 300mV reference. This low reference voltage allows monitoring voltages lower than those supported by previous supervisor ICs.
The reset output is asserted for no less than 140ms at poweron and any time the input voltage drops below the reference voltage. It remains asserted for the timeout period after the input voltage subsequently rises back above the threshold boundary. A reset can be generated at any time by asserting the manual reset input, /MR. The reset output will remain active at least 140ms after the release of /MR. The /MR input can also be used to daisy-chain the MIC2776 onto existing power monitoring circuitry or other supervisors. Hysteresis is included to prevent chattering due to noise. Typical supply current is a low 3.0μA.

Microchip Technology MIC24097評估板經(jīng)過完全組裝和測試,用于演示MIC24097的功能。MIC24097轉換器采用出色的自適應導通時間控制架構。該板基于降壓拓撲,當輸入端配有5V至20V電壓時,可提供1V輸出電壓,最大電流為20A。
高通的QCC304x及后續(xù)的芯片支持HybridANC,包含F(xiàn)FMIC和FBMIC。其中FFMIC可以與2-CVC中的副MIC共用同一個MIC,可以是數(shù)字MIC或者模擬MIC。但是如果是模擬MIC的話,因為ANC與CVC會共用FFMIC的模擬增益。
