5 / 19 page TD62650,651,652FG 2006-06-14 5 PIN FUNCTION PIN No. PIN NAME PIN FUNCTION 1 GND GND pin for 5 V power supply and supply monitoring. 2 COMP Phase compensation pin for output stabilization. 3 VCCIN Power supply pin for internal circuit. The output voltage can also be detected at this pin. 4 VCCOUT Output pin for built−in Power Tr, having a current capacitance of 300 mA (max). It is also used as an output pin for 5 V constant power supply through shorting with VCCIN pin. 5 OUT Connected to the base of an external PNP transistor so that the output voltage is stabilized. Current design suitable for load capacities is thus possible. Since the recommended IOUT current is 5 mA, an output current of 300 mA is assured if the external transistor has an hFE of 60. When the internal transistor is used, it can be opened. 6 BIAS Power supply starting pin. The starting current is supplied through a resistor to which the input voltage is applied. When VCCIN rises above 3.0 V, the starting current is absorbed in the internal circuit ; instead, IOUT is supplied via VCCIN. 7 VCC2 Power supply pin for the 24−V system. 8 SLSYN Input pin for the 24−V system interface. Pull−up resistor 47 kΩ is incorporated at VCC2 pin. 9 50 / 60 Input pin for 24−V system interface. Pull−up resistor 47 kΩ is incorporated at VCC2 pin. 10 MSSYN Output pin for the 24−V system open collector. 11 CPUOUT Input pin for the 5−V system Push / Pull inverter. Pull−up resistor 30 kΩ is incorporated at VCCIN pin. 12 LED LED lighting pin for the 8 system open collector. 680 Ω limiting resistor is incorporated. 13 TXD Output pin for the 24−V system open collector. 14 RXD Input pin for the 24−V system interface. Pull−up resistor 47 kΩ is incorporated at the VCC2 pin. 15 PG GND pin for the 5−V / 24−V system interfaces. 16 SLTXD Output pin for the 5−V system open collector. Pull−up resistor 4.7 kΩ is incorporated at the VCCIN pin. 17 MSRXD Output pin for the 5−V system Push−Pull buffer. 18 MSTXD Input pin for the 5−V system interface, for input at LED (12 pin) and TXD (13 pin) pins. 19 TXDOUT Output pin for the 5−V system Push / Pull inverter (CPUOUT : 11 pin). 20 SYNIN Input pin for the 5−V system interface. 21 MS50 / 60 Output pin for the 5−V system open collector. Pull−up resistor 4.7 kΩ is incorporated at VCCIN pin. 22 SL50 / 60 Output pin for the 5−V system Push / Pull buffer. 23 SYN Output pin for the 5−V system Push−Pull buffer. 24 HNSYN Output pin for the 5−V system open collector. Pull−up resistor 4.7 kΩ incorporated at VCCIN pin. 25 CCK Output pin for the 5−V system Push−Pull buffer. |
