FAN8025G3 Fairchild Semiconductor, FAN8025G3 Datasheet - Page 9

• Manufacturer Part Number: FAN8025G3
• Manufacturer: Fairchild Semiconductor

Specifications of FAN8025G3

• Operating Temperature Classification: Commercial
• Package Type: SSOPH-375SG2
• Operating Supply Voltage (min): 4.5V
• Operating Supply Voltage (max): 13.2V
• Lead Free Status / Rohs Status: Compliant

Application Information
1. Reference Input
• Reference input (PIN 22)
2. Stand-by Function
• MUTE input (PIN 23)
3. Protection Function
Thermal shutdown (TSD)
When the chip temperature rises above 175 C, the thermal shutdown (TSD) circuit is activated and the output circuit is in the
mute state, that is off state. The TSD circuit has a temperature hysteresis of 25 C
4. Separation Of Power Supply
• VCC2 (PIN 24)
• VCC1 (PIN 19)
VCC1 input voltage must be higher than or same to VCC2. (VCC1 VCC2)
The applied voltage at the reference input pin must be ranged between 1.0V and 3.3V, when V
When the reference input voltage goes below 0.7V, all channels are disabled.
We recommend CH1 as the loading(or tray) motor driver. Detailed logic table is as below.
VCC2 is the power supply for CH4 and CH5, which are current feedback drivers.
VCC1 is the power supply for CH1, CH2, CH3 and predriver.
