(the standard current depends on en pin pull-down resistance.) 3. it shows current dissipation of v cc pin in state of en = 5v (stand-by), including current dissipation of vg pin. 4. for in1, in2, in3 and in4 pins, no pull-down and pull-up resistance is needed. (high impedance pin) 5. it shows sum of upper and lower saturation voltages of out pin. 6. it controls charge-pump oscillation and makes specified voltage. 7. when low voltage is detected, the lower output is turned off. 8. when thermal protection circuit is activated, the lower output is turned off. when the heat temperature is fa llen, it is turned on again. 9. ig (vg pin load current) = 500 a 10. it shows vg pin current dissipation in state of pwm input for in pin. 11. it specifies start-up time from 10 % to 90 % when vg is in non-load state (when setting the capacitor between vg and gnd to 0.1 f and v cc is 5v). 12. it specifies 10 % to 90 % for start-up and 90 % to 10 % for shut-down.
