outputs: V1, V2
ƒ Over-current Protection (OCP) for 5V, 12V, and two
outputs: V1, V2
ƒ Adjustable Voltage Control Sense Input of V1 and
V2 (ADJ-V1, ADJ-V2)
ƒ Open-drain Output for FPO Pin
ƒ 13ms PSON Control Delay
ƒ No Lockup During the Fast AC Power-on/off
ƒ Wide Supply Voltage Range: 4V to 15V
ƒ Programmable Over-temperature Protection (OTP)
Description
SG6518 provides the over-voltage protection (OVP) for
5V, 12V, and outputs V1 and V2 as well as over-current
protection (OVP) for 5V, 12V, and outputs V1 and V2.
When the voltage of OTP pin decreases to 1.2V, the
over-temperature protection (OTP) function is enabled.
FPO is set to HIGH to turn off the PWM control IC. The
voltage difference across the external current shunt is
used for OCP functions. An external resistor can be
used to adjust protection threshold.
The power supply is turned on after a 13ms delay time
when the PSON signal is set from LOW to HIGH. To
turn off the power supply, PSON signal is set from
HIGH to LOW with the delay time 13ms.
