Microchip Technology MIC94092
The MIC94092 and MIC94093 provide a slew rate controlled soft-start turn-on of 790 μs, while the MIC94094 and MIC94095 provide a slew rate controlled soft-start turn-on of 120 μs. The soft-start feature option prevents an in-rush current event from pulling down the input supply voltage. The MIC94091, MIC94093, and MIC94095 include a 250Ω auto discharge load circuit that is switched on when the load switch is disabled.APPLICATIONS
