PRODUCTION DATA
By connecting a fixed-value thermistor between [TCOMP and GND] and a fixed-value pull-up resistor between [VL and TCOMP], the VGH voltage will vary from a given VGH_LT voltage below a pre-defined (by external resistors) 'low' temperature to a lower voltage defined by VGH_HT for 'high' temperatures (also set by the same external resistors). The user has to provide VGH_LT and VGH_HT.
The internal temperature compensation system for VGH is made to work only with 47 kΩ NTC part number NCP18WB473F10RB. The other resistors could possibly be adjusted to match other temperatures but would affect the P-Vcom temperature compensation.
