Abstract: A microelectronic device including an integrated boot diode and a depleted mode LDMOS transistor with a charge balance layer isolated from the body region and electrically in contact with a substrate. The connection of the charge balance layer of the depleted mode LDMOS transistor directly to the substrate or ground reference eliminates body diode turn-on from the body of the transistor to the drain which typically happens above approximately 0.7 volts. In addition, the depleted mode LDMOS transistor may separate a source contact from a body contact which allows a negative bias of the body with respect to the source. Typically, the source voltage is limited to approximately 7 volts before parasitic PNP turn on becomes a factor. By negatively biasing the body with respect to the source, the maximum source voltage of the depleted mode LDMOS transistor without PNP parasitic turn-on may be increased to approximately 30 V.
