bts 7810 k data sheet 5 2003-03-11 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 ds on power-mos h-bridge. in h-bridge 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-voltage- drop 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 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. 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.
bts 7810 k data sheet 6 2003-03-11 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 ol is disconnected from 5v by bcr192w. 2 truthtable and diagnosis (valid only for the high-side-switches) flag ih1 ih2 sh1 sh2 st1 st2 remarks inputs outputs normal operation; identical with functional truth table 0 0 1 1 0 1 0 1 l l h h l h l h 1 1 1 1 1 1 1 1 stand-by mode switch2 active switch1 active both switches active open load at high-side switch 1 open load at high-side switch 2 0 1 x x x x 0 1 z h x x x x z h 0 1 1 1 1 1 0 1 detected detected overtemperature high-side switch1 0 1 x x l l x x 1 0 1 1 detected overtemperature high-side switch2 x x 0 1 x x l l 1 1 1 0 detected overtemperature both high-side switches 0 x 1 0 1 x l l l l l l 1 1 0 1 0 1 detected detected undervoltage x x l l 1 1 not detected note: * multiple simultaneous errors are not shown in this table inputs: outputs: status: 0 = logic low z = output in tristate condition 1 = no error 1 = logic high l = output in sink condition 0 = error x = don?t care h = output in source condition x = voltage level undefined
