BTS 781 GP Q67006-A9526 P-TO263-15-1
1.2 Description
The BTS 781 GP is part of the TrilithIC family containing three dies in one package: One double high-side switch and two low-side switches. The drains of these three vertical DMOS chips are mounted on separated leadframes. The sources are connected to individual pins, so the BTS 781 GP can be used in H-bridge- as well as in any other configuration. The double high-side is manufactured in SMART SIPMOS which combines low
R
vertical DMOS power stages with CMOS control circuit. The
DS ON
®
technology
high-side switch is fully protected and contains the control and diagnosis circuit. To achieve low
R
and fast switching performance, the low-side switches are
DS ON
manufactured in S-FET 2 logic level technology. The equivalent standard product is the SPD30N06S2L-13.

1.6 Circuit Description
Input Circuit
The control inputs IH1,2 consist of TTL/CMOS compatible Schmitt-Triggers with hysteresis. Buffer amplifiers are driven by these stages and convert the logic signal into the necessary form for driving the power output stages. The inputs are protected by ESD clamp-diodes.
The inputs IL1 and IL2 are connected to the gates of the standard N-channel vertical power-MOS-FETs.
Output Stages
The output stages consist of a low
R
Power-MOS H-bridge. In H-bridge
DS ON
configuration, the D-MOS body diodes can be used for freewheeling when commutating inductive loads. If the high-side switches are used as single switches, positive and negative voltage spikes which occur when driving inductive loads are limited by integrated power clamp diodes.
Short Circuit Protection
The outputs are protected against
– output short circuit to ground – overload (load short circuit).
An internal OP-amp controls the Drain-Source-voltage by comparing the DS-voltage­drop with an internal reference voltage. Above this trippoint the OP-Amp reduces the output current depending on the junction temperature and the drop voltage.
In the case of overloaded high-side switches the status output is set to low.
Overtemperature Protection
The high-side switches incorporate an overtemperature protection circuit with hysteresis which switches off the output transistors and sets the status output to low.
Undervoltage-Lockout (UVLO)
When VS reaches the switch-on voltage V The high-side output transistors are switched off if the supply voltage switch off value

the IC becomes active with a hysteresis.
UVON

drops below the
S
Open Load Detection
Open load is detected by voltage measurement in off state. If the output voltage exceeds a specified level the error flag is set with a delay.
Data Sheet 5 2002-06-28
Page 6
BTS 781 GP
Status Flag
The two status flag outputs are an open drain output with Zener-diode which require a pull-up resistor, c.f. the application circuit on page 15. ST1 and ST2 provide separate diagnosis for each high-side switch. Various errors as listed in the table “Diagnosis” are detected by switching the open drain output ST1/2 to low. Forward current in the integrated body diode of the highside switch may cause undefined voltage levels at the corresponding status output. The open load detection can be used to detect a short to Vs as long as both lowside switches are off and R BCR192W.
