All Rights Reserved. 7 MP6211/MP6212 –CURRENT-LIMITED POWER DISTRIBUTION SWITCHES DETAILED DESCRIPTION Over Current When the load exceeds trip current (minimum threshold current triggering constant-current mode) or a short is present, MP6211/MP6212 switches into to a constant-current mode (current limit value). MP6211/MP6212 will be shutdown only if the overcurrent condition stays long enough to trigger thermal protection. Trigger overcurrent protection for different overload conditions occurring in applications: 1) The output has been shorted or overloaded before the device is enabled or input applied. MP MP6211/MP6212 detects the short or overload and immediately switches into a constant-current mode. 2) A short or an overload occurs after the device is enabled. After the current-limit circuit has been tripped (reached the trip current threshold), the device switches into constantcurrent mode. However, high current may flow for a short period of time before the current-limit circuit can react. Thermal Protection The purpose of thermal protection is to prevent damage in the IC by allowing exceptive current to flow and heating the junction. The die temp. is internally monitored until the thermal limit is reached. Once this temp. is reached, the switch will turn off and allow the chip to cool. The switch has a built-in hysteresis. Under-voltage Lockout (UVLO) This circuit is used to monitor the input voltage to ensure that the MP6211/6212 is operating correctly. This UVLO circuit also ensures that there is no operation until the input voltage reaches the minimum spec. Enable The logic pin disables the chip to reduce the supply current. The device will operate once the enable signal reaches the appropriate level. The input is compatible with both COMS and TTL. 3) Output current has been gradually increased beyond the recommended operating current. The load current rises until the trip current threshold is reached or until the thermal limit of the device is exceeded. The MP6211/ MP6212 is capable of delivering current up to the trip current threshold without damaging the device. Once the trip threshold has been reached, the device switches into its constant-current mode. Flag Response The FLAG pin is an open drain configuration. This FAULT will report a fail mode after an 8ms deglitch timeout. This is used to ensure that no false fault signals are reported. This internal deglitch circuit eliminates the need for extend components. The FLAG pin is not deglitched during an over temp. or a voltage lockout.

All Rights Reserved. 8 MP6211/MP6212 –CURRENT-LIMITED POWER DISTRIBUTION SWITCHES APPLICATION INFORMATION In order to achieve smaller output load transient ripple, placing a high-value electrolytic capacitor on the output pin(s) is recommended when the load is heavy. Power-Supply Considerations Over 10μF capacitor between IN and GND is recommended. This precaution reduces powersupply transients that may cause ringing on the input and improves the immunity of the device to short-circuit transients. +5V 1 GND MP6212 2, 3 IN 4 EN OUT 6, 7 To VBUS USB Ports FLAG 5 SINGLE-CHANNEL Figure 3—Application Circuit MP6211_MP6212 Rev. 1.3 www.MonolithicPower.com 7/16/2019 MPS Proprietary Information.
