SNOSDF9B July 2023 – March 2024 LMG2100R044
PRODUCTION DATA
The LMG2100R044 operates in normal mode and UVLO mode. See Section 7.3.2 for information on UVLO operation mode. In the normal mode, the output state is dependent on the states of the HI and LI pins. Table 7-3 lists the output states for different input pin combinations. Note that when both HI and LI are asserted, both GaN FETs in the power stage are turned on. Careful consideration must be applied to the control inputs in order to avoid this state, as it will result in a shoot-through condition, which can permanently damage the device.
HI | LI | HIGH-SIDE GaN FET | LOW-SIDE GaN FET | SW |
---|---|---|---|---|
L | L | OFF | OFF | Hi-Z |
L | H | OFF | ON | PGND |
