ZHCSHN8B February 2018 – October 2018 LMG1020
PRODUCTION DATA.
LMG1020 features nominal 5V and maximum 5.25V of supply voltage, and its absolute maximum supply voltage is 5.75 V. In the design, it is recommended to limit the variability of the power supply to be within 5% (0.25V), and the overshoot voltage during switching transient not to exceed the absolute maximum voltage. Refer to Section VDD and Overshoot for more the detailed design guide.
LMG1020 also features internal undervoltage lockout (UVLO) to protect the driver and circuit in case of fault conditions. The UVLO point is setup between 4.1V and 4.2V with a hysteresis of 85mV. This UVLO level is specifically designed to guarantee that GaN power devices can be switched at a low RDS(ON) region. During UVLO condition, the OUTL is pulled down to ground.
