Customer Information BTS7800K / BTS781GP Munich, 6th July 2001 Change in TrilithIC product portfolio BTS7800K / BTS781GP - update Dear Customer, during the last year we offered the BTS7800K as standard replacement for BTS780GP and BTS780GP-2. Our intention was to have the same pin out of BTS7800K and the other TrilithICs BTS7710GP and BTS7750GP. Therefore BTS7800K requires a different PCB layout than the BTS780GP. In order to make a replacement of BTS780GP easier in existing projects we offered the same chip as BTS7800K with a pin out compatible to BTS780GP PCB layouts called BTS781GP. Following the feedback of our customers, who ordered mainly BTS781GP, we decided not to release BTS7800K. The standard replacement for BTS780GP and BTS780GP-2 is therefore now BTS781GP. All features of BTS781GP are identical to the features of BTS7800K. Also open load detection in off state is implemented. In addition to that a separated status output for each high side switch is offered. With these 2 changes, the BTS781GP is identical to BTS780GP in all main features. The time schedule of the project remains unchanged. Engineering / quality samples: 09/01 Delivery release: 02/02 Please find more detailed information on the following pages.

Open load detection in on state removed. PWM: Clearly improved PWM behavior - No cross currents up to VBB=36V / 20kHz Quiescent current: Reduced from 30 to 8A Over-voltage lockout: Removed in BTS781GP AI AP APE Koppl / Blanke Page 1 Semiconductors for AUTOMOTIVE SOLUTIONS TRILITHICs Differencies BTS781GP to BTS780GP RDSon: Type Ron / HS Max. @ 25C Ron / LS Max. @ 25C Ron / Path Max. @150C BTS780GP BTS7800K BTS781GP 40 35 35 20 15 15 110 100 100 AI AP APE Koppl / Blanke Page 2 Semiconductors for AUTOMOTIVE SOLUTIONS TRILITHICs Differencies BTS781GP to BTS780GP ISCP_H: Current limitation of highside switch Type ISCP_H [A] Min. @ -40C ISCP_H [A] Min. @ 25C ISCP_H [A] Min. @ 150C BTS780GP BTS7800K BTS781GP 47 (40) (40) 35 (35) (35) 21 25 25 AI AP APE Koppl / Blanke Page 3 Semiconductors for AUTOMOTIVE SOLUTIONS !
