They are used to control up to 3 different loads by a microcontroller in automotive and industrial applications. Each of the 3 high-side and 3 low-side drivers is capable to drive currents up to 1.5 A. The drivers are internally connected to form 3 half-bridges and can be controlled separately from a standard serial data interface. Therefore, all kinds of loads such as bulbs, resistors, capacitors and inductors can be combined. The IC design especially supports the application of H-bridges to drive DC motors. Triple Halfbridge DMOS Output Driver with Serial Input Control T6818/T6828 Protection is guaranteed regarding short-circuit conditions, overtemperature and under voltage. Various diagnostic functions and a ver y low quiescent current in stand-by-mode opens a wide range of applications. Automotive qualification (protection against conducted interferences, EMC protection and 2-kV ESD protection) gives added value and enhanced quality for exacting requirements of automotive applications.

Data must appear at DI synchronized to CLK and are accepted on the falling edge of the CLK signal. LSB (bit 0, SRR) has to be transferred first. Execution of new input data is enabled on the rising edge of the CS signal. When CS is high, pin DO is in tri-state condition. This output is enabled on the falling edge of CS. Output data will change their state with the rising edge of CLK and stay stable until the next rising edge of CLK appears. LSB (bit 0, TP) is transferred first. Figure 3.

To detect an undervoltage, its duration has to last longer than the undervoltage detection delay time tdUV. The outputs are enabled immediately when supply voltage recovers normal operation value. The PSF bit stays high until it is reset by the SRR bit in the input register. Open-load Detection If the current through a high-side or low-side switch in ON-state stays below the openload detection threshold, the open-load detection bit (OPL) in the output register is set. The OPL bit stays high until it is reset by the SRR bit in the input register. To detect an open load, its duration has to last longer than the open-load detection delay time tdSd. Overtemperature Protection If the junction temperature of one or more output stages exceeds the thermal prewarning threshold, TjPW set, the temperature prewarning bit (TP) in the output register is set. When the temperature falls below the thermal prewarning threshold, TjPW reset, the bit TP is reset. The TP bit can be read without transferring a complete 16-bit data word. The status of TP is available at pin DO with the falling edge of CS. After the microcontroller has read this information, CS is set high and the data transfer is interrupted without affecting the status of input and output registers. If the junction temperature of one or more output stages exceeds the thermal shutdown threshold, Tj switch off, all outputs are disabled and the corresponding bits in the output register are set to low. The outputs can be enabled again when the temperature falls below the thermal shutdown threshold, Tjswitch on and the SRR bit in the input register is set to high. Hysteresis of thermal prewarning and shutdown threshold avoids oscillations. Short-circuit Protection The output currents are limited by a current regulator. Overcurrent detection is activated by writing a high to the OCS bit in the input register. When the current in an output stage exceeds the overcurrent limitation and shutdown threshold, it is switched off after a delay time (tdSd). The short-circuit detection bit (SCD) is set and the corresponding status bit in the output register is set to low. For OCS = low the overcurrent shutdown is inactive. The SCD bit is also set if the current exceeds the overcurrent limitation and shutdown threshold, but the outputs are not affected. By writing a high to the SRR bit in the input register the SCD bit is reset and the disabled outputs are enabled. Inhibit 0 V applied to pin 10 (INH) inhibits the T6818/T6828. All output switches are then turned off and switched to tri-state. The data in the output register are deleted. The current consumption is reduced to less than 5 µA at pin VS and less than 25 µA at pin VCC. The output switches can be activated again by switching pin 10 (INH) to 5 V which initiates an internal power-on reset. 6 T6818/T6828 4530E–BCD–07/04 T6818/T6828 Absolute Maximum Ratings Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Recommended value for capacitors at VS: Electrolytic capacitor C > 22 µF in parallel with a ceramic capacitor C = 100 nF. Value for electrolytic capacitor depends on external loads, conducted interferences and reverse conducting current IOut1,2,3 (see “Absolute Maximum Ratings” on page 7). Recommended value for capacitors at VCC: Electrolytic capacitor C > 10 µF in parallel with a ceramic capacitor C = 100 nF. To reduce thermal resistance it is recommended to place cooling areas on the PCB as close as possible to the GND pins. Negative spikes at the output pins (e.g. negative spikes caused by an inductive load switched off with a high side driver) may activate the overtemperature protection function of the T6818/T6828. In this condition, all outputs will be switched off simultaneously. If this behavior is not acceptable or compatible with your application functionally, it is necessary, that for switching on required outputs again, the SRR bit (Status Register Reset) is set, to ensure a reset of the overtemperature function. 13 4530E–BCD–07/04 Ordering Information Extended Type Number Package Remarks T6818-TUS SO14 Power package, tubed T6818-TUQ SO14 Power package, taped and reeled T6828-T2S SO14 Power package with heat slug, tubed T6828-T2Q SO14 Power package with heat slug, taped and reeled Package Information Package SO14 5.2 4.8 Dimensions in mm 8.75 3.7 1.4 0.25 0.10 0.4 1.27 6.15 5.85 7.62 14 0.2 3.8 8 technical drawings according to DIN specifications 1 14 7 T6818/T6828 4530E–BCD–07/04 T6818/T6828 15 4530E–BCD–07/04 Revision History Please note that the following page numbers referred to in this section refer to the specific revision mentioned, not to this document.
