Description
4.1.2
Current Regulator: Peak Current Control with Fixed Off-Time
Hold only: When channel turned externally (SPI parallel input) current rises programmed hold current level. Then channel internally turned timer started fixed off-time (e.g. µs). After this time channel internally turned again until hold current level reached again This regulation works automatically until channel turned externally. Peak hold mode with minimum peak time: When channel turned current rises programmed peak current level. Then channel internally turned off, current regulator changes hold current values timer started constant off-time. After this time channel internally turned again until hold current value reached then again turned fixed time. This regulation works automatically until channel turned externally. Peak hold mode with programmed peak time: When channel turned current rises programmed peak current level. Then channel internally turned timer started fixed offtime. After this time channel internally turned again until peak current value reached then again turned off. This works until programmed peak time over. Then current regulator changes hold current values works described under "hold only".
Peak Current, Peak Time, Hold Current fixed Off-Time SPI. avoid regulation disturbances current transients during switching (e.g. caused capacitors outputs) current regulator "leading edge blanking" typical three regulation modes. After turning DMOS (internally externally) current regulation circuit deactivated first This guarantees that switching DMOS itself charging small capacitors output (e.g. ESD) disturbing current regulation. detect shorted loads inductance loads three regulation modes timer started when channel turned (tli). first rising edge load current reaches programmed current level (peak hold current depending configured current control mode) within this time overload fault reported (see Chapter 7.3).

Protection
TLE6288R integrated protection functions1) overload short circuit (active current limitation), overtemperature, pins overvoltage power outputs (zener clamping). Overtemperature Behavior Each channel overtemperature sensor individually protected against overtemperature. soon overtemperature occurs channel immediately turned off. this case there different behaviors affected channel that selected (for channels generally): Autorestart: long input signals channel remains (e.g. parallel input high) channel turns automatically again after cooling down. Latching: After overtemperature shutdown channel stays until this overtemperature latch reset transition input signal. Note: These overtemperature sensors channels only active channel turned additional overtemperature sensor located logic device. monitors permanently temperature. soon temperature reaches specified level overtemperature fault will indicated.
Integrated protection functions designed prevent destruction under fault conditions described data sheet. Fault conditions considered "outside" normal operating range. Protection functions designed continuous repetitive operation.
