40 product specifications block diagram block diagram power mosfet gate driver for h-bridge circuit built-in power mosfet protecrion and diagnosis functions: overvoltage and low-voltage protedtion built-in a charge pump circuit. package: ssop-24 (300 mil) with embossed-tape packing power mosfet gate driver for h-bridge TPD7202F is a power mosfet gate driver for h-bridge circuit using charge pump system. because this ic contains a charge pump circuit for high-side drive, it allows you to configure h-bridge circuit. (*1): optimum conditions depend on switching loss, emi, etc. of external mosfet. (*2): sbd v f = 0.5 v max (recommended: crs03) this is need when the m+ or m- pin is biased to the negative side by more than 0.5 v. (*3): this is a laminated ceramic capacitor. (*4): high-speed diode t rr = 100 ns max (recommended: crh01) 5 6 8 3 22 17 16 10 15 13 1 2 11 vb reverse connection protection overvoltage protection circuit low-voltage protection circuit charge pump osc 5 v power supply logic circuit cpu out1 m+ out2 m out3 out4 pgnd sgnd fault in1 in2 in3 in4 v dd c osc r osc cp1 cp2 cpv (*4) (*4) (*3) (*3) (*3) (*4) 12 24 (*1) (*2) (*1) (*2) (*1) (*1) + 10 f / 50 v 1 f 0.47 f 0.47 f 1500 pf 100 k ? 10 k ?
