9 / 12 page LC898122AXA www.onsemi.com 9 Driver 1) Absolute Maximum Ratings Parameter Symbol Condition Ratings Symbol Power supply voltage VMmax 4.6 V Output peak current Iopeak OUT1 to 4 t ≤ 10ms, ON-duty ≤ 20% 300 mA OUT5, OUT6 t ≤ 10ms, ON-duty ≤ 20% 200 mA Output continuous current Iomax OUT1 to 4 220 mA OUT5,OUT6 150 mA 2) Operating Range Parameter Symbol Condition Ratings Symbol Ambient temperature Topg 30 to +85 C Power supply voltage VM 2.6 to 3.6 V 3) H-Bridge Driver Output at Ta=25 C, VM=3.0V Parameter Symbol Condition Ratings (Ω) Symbol Output ON resistance OUT1 to OUT4 Ronu Io=220mA(Pch) 2.0 Ω Rond Io=220mA(Nch) 1.0 Ω Output ON resistance OUT5, OUT6 Ronu Io=150mA(Pch) 1.0 Ω Rond Io=150mA(Nch) 2.0(*) Ω (*) include Constant current detect resistance 4) Constant Current Open-AF Driver output at Ta=25 C, VM=2.8V condition 1 condition 2 output current *1 DAC code of AF Driver AF_D[9:0] DAC gain of AF Driver DGAINDAF(0083h[6:4]) (AF_GAIN_D[2:0]) typ OUT5, OUT6 3FFh (Full Code) 4 150mA *1 output current is calculated by registance of VCM and (the drain-source voltage of Nch Driver Tr) + (sense registance voltage). ex. In the case of "VM=3V" and "output current=100mA" (the drain-source voltage of Nch Driver Tr) + (sense registance voltage)= max 0.5V. VCM registance (Rvcm) = (2.8-0.5) / 0.1 = 23Ω Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended Operating Ranges limits may affect device reliability. |
