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 MP6233 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.
