SG6518 — LCD Power Supply Supervisor December 2007 SG6518 LCD Power Supply Supervisor Features ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ Two Adjustable Voltage Sense Input Pins: VSV1 and VSV2 Over-voltage Protection (OVP) for 5V, 12V, and two outputs: V1, V2 Over-current Protection (OCP) for 5V, 12V, and two outputs: V1, V2 Adjustable Voltage Control Sense Input of V1 and V2 (ADJ-V1, ADJ-V2) Open-drain Output for FPO Pin 13ms PSON Control Delay No Lockup During the Fast AC Power-on/off Wide Supply Voltage Range: 4V to 15V 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.
