Both the high-side and the low-side driver stages include UVLO protection circuitry which monitors the supply voltage (V_GVDD) and the bootstrap capacitor voltage (V_BST-SH). The UVLO circuit inhibits each output until sufficient supply voltage is available to turn on the external MOSFETs, and the built-in UVLO hysteresis prevents chattering during supply voltage variations. When the supply voltage is applied to the GVDD pin of the device, both outputs are held low until V_GVDD exceeds the UVLO threshold, typically 8 V. Any UVLO condition on the bootstrap capacitor (V_BST–SH) disables only the high-side output (GH).
