The drains of these three vertical DMOS chips are mounted on separated lead frames. The sources are connected to individual pins, so the BTM770GP can be used in H-bridge- as well as in any other configuration. The double high-side switch is manufactured in SMART SIPMOS technology which combines low R DS ON vertical DMOS power stages with CMOS circuitry for control, protection and diagnosis. To achieve low R DS ON and fast switching performance, the low-side switches are manufactured in S-FET logic level technology. Type Package Marking BTM770GP PG-TO BTM770GP Datasheet 3 Rev..0,

8 BTM770GP 4 Circuit Description 4. Input Circuit The control inputs IH,2 consist of TT/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 I and I2 are connected to the gates of the standard N-channel vertical power-mos-fets. 4.2 Output Stages The output stages consist of an low R DSON Power-MOS H-bridge. In H-bridge configuration, the D-MOS body diodes can be used for freewheeling when communicating 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. 4.3 Short Circuit Protection The outputs are protected against short circuit to ground and short circuit over load An internal OP-Amp controls the Drain-Source-Voltage by comparing the DS-Voltage-Drop with an internal reference voltage. Above this trip point the OP-Amp reduces the output current depending on the junction temperature and the drop voltage. 4.4 Overtemperature Protection The high-side switches also incorporate an over temperature protection circuit with hysteresis which switches off the output transistors and sets the status output to low. 4.5 Undervoltage ockout When V S reaches the switch-on voltage V UVON the IC becomes active with a hysteresis. The high-side output transistors are switched off if the supply voltage V S drops below the switch off value V UVOFF. 4.6 Status Flag The status flag output is an open drain output with zener-diode which requires a pull-up resistor, as shown in the application circuit in Figure 4 Application Example BTM770GP on Page 5. Various errors as listed in the table Diagnosis are reported by switching the open drain output ST to low. Datasheet 8 Rev..0,
