ADVANCE INFORMATION
An internal trickle charge pump (TCP) is connected to BST node to reduce voltage drop due to the leakage currents of the driver and external components. The charge pump generates VTCP voltage with respect to VDRAIN pin. For the independent PWM mode, the charge pump is active all the time. For the 2-pin PWM and 1-pin PWM mode, if the INL stays low for 250us (typ), the charge pump is activated.
