PARAMETER TEST CONDITIONS MIN TYP MAX UNIT OC and OLP ILIM N-Channel MOSFET current limit D = Dmax 0.56 0.7 0.84 A ILIM_Start Start up current limit D = Dmax 0.4 A tHalf_LIM Time step for half current limit 5 ms Vovp Open LED protection threshold Measured on the SW pin, TPS61160 TPS61161 25 37 26 38 27 39 V V(FB_OVP) Open LED protection threshold on FB Measured on the FB pin, percentage of VREF VREF= 200 mV and 20 mV 50% VACKNL Acknowledge output voltage low Open drain, Rpullup =15 kΩ to VIN 0.4 V THERMAL SHUTDOWN Tshutdown Thermal shutdown threshold 160 °C Thysteresis Thermal shutdown threshold hysteresis 15 °C (1) Acknowledge condition active 0, this condition will only be applied in case the RFA bit is set. Open drain output, line needs to be pulled high by the host with resistor load. (2) To select EasyScale mode, the CTRL pin has to be low for more than tes_det during tes_win. 6.6 Timing Requirements MIN NOM MAX UNIT OC and OLP tREF VREF filter time constant 180 μs tstep VREF ramp up time 213 μs EasyScale tvalACKN Acknowledge valid time(1) 2 μs tACKN Duration of acknowledge condition(1) 512 μs toff CTRL pulse width to shutdown, CTRL high to low 2.5 ms tes_det Easy Scale detection time(2) 260 μs tes_delay EasyScale detection delay, Measured from CTRL high 100 μs tes_win EasyScale detection window time 1 ms tSTART Start time of program stream 2 μs tEOS End time of program stream 2 360 μs tH_LB High time low bit, logic 0 2 180 μs tL_LB Low time low bit, logic 0 2 × tH_LB 360 μs tH_HB High time high bit, logic 1 2 × tL_HB 360 μs tL_HB Low time high bit, logic 1 2 180 μs |
