In addition to overcurrent protection, an added feature is the voltage monitoring on the two lines. If the voltage on the line drops below Vss then the voltage will trigger the device to switch to the blocking state. Vdd Line 1 SLIC Line 1 Line 2 SLIC Line 2 Vss The TBU® high speed protector placed in the system circuit will monitor the current with the MOSFET detection circuit triggering to provide an effective barrier behind which sensitive electronics will not be exposed to large voltages or currents during surge events. The TBU® device is provided in a surface mount DFN package and meets industry standard requirements such as RoHS and Pb Free solder reflow profiles.

Where necessary, an OVP device should be employed to limit the maximum voltage. A cost-effective protection solution combines Bourns® TBU® protection devices with a pair of Bourns® MOVs. For bandwidth sensitive applications, a Bourns® GDT may be substituted for the MOV. GND Vdd Line 1 Line 1 SLIC TBU® Device Vss -VBAT The TBU® device, constructed using MOSFET semiconductor technology, placed in the system circuit will monitor the current with the MOSFET detection circuit triggering to provide an effective barrier behind which sensitive electronics are not exposed to large voltages or currents during surge events. The TBU® device operates in approximately 1 µs - once line current exceeds the TBU® device’s trigger current Itrigger. When operated, the TBU® device restricts line current to less than 1 mA typically. When operated, the TBU® device will block all voltages including the surge up to rated limits. When the voltage on the SLIC output is driven below (Vbat – Vto) the TBU-PL series device switches to the blocking state, regardless of output current in the device. After the surge, the TBU® device resets when the voltage across the TBU® device falls to the Vreset level. The TBU® device will automatically reset on lines which have no DC bias or have DC bias below Vreset (such as unpowered signal lines). MOV Line 2 SLIC Line 2 MOV Line 2 If the line has a normal DC bias above Vreset, the voltage across the TBU® device may not fall below Vreset after the surge. In such cases, special care needs to be taken to ensure that the TBU® device will reset, with software monitoring as one method used to accomplish this. Bourns application engineers can provide further assistance. Specifications are subject to change without notice. Customers should verify actual device performance in their specific applications.
