[External Components]
CPH6315 (P-ch MOSFET: SANYO), IRLMS6702 (P-ch MOSFET: IR)
CPH3409 (N-ch MOSFET: SANYO), IRLMS1902 (N-ch MOSFET: IR)
CPH3409 (N-ch MOSFET: SANYO), IRLMS1902 (N-ch MOSFET: IR)
Vgs Breakdown Voltage of CHPH6315 and CPH3409 is 10V so please be
careful with the power supply voltage.
For the power supply voltage more than 8V, CPH3308 (P-ch MOSFET: SANYO)
or CPH3408 (N-ch MOSFET: SANYO) which breakdown voltage is 20V are
recommended.
