APPLICATION INFORMATION

OUTPUT DRIVERS
The totem-pole output drivers of the SG1526 are designed to source and sink 100mA continuously and 200mA peak. Loads
can be driven either from the output pins 13 and 16, or from the +V
pin, as required. Curves for the saturation voltage at these
outputs as a function of load current are found in Figures 14 and 15.
Since the bottom transistor of the totem-pole is allowed to saturate, there is a momentary conduction path from the +V
terminal
to ground during switching. To limit the resulting current spikes a small resistor in series with pin 14 is always recommended.
The resistor value is determined by the driver supply voltage, and should be chosen for 200mA peak currents, as shown in
Figure 25.
