BASICAPPLICATION
TheRBO has 3functionsintegratedonthe same
chip.
3
D1 : “Diode function” in order to protect against
reversedbattery operation.
T2: “Transil function” in order to protectagainst
positive surge generated by electric systems
(ignition,relay. ...).
T1: Protectionformotor drive application
(Seebelow).
* The monolithic multi-function protection
(RBO) has been developed to protect
sensitivesemiconductorsin car electron ic
modules against both overvoltage and
batteryreverse.
* In addition, the RBO circuit prevents
overvoltages generated by the module from
affecting the carsupply network.
