UNISONIC TECHNOLOGIES CO., LTD 3510 CMOS IC PC POWER SUPPLY SUPERVISORS DESCRIPTION The UTC 3510 is designed to provide protection circuits, power good output (PGO) indicator, fault protection output (FPO) and a PSON control for PC switching power supply systems. The protection circuits include over voltage protection (OVP) monitoring for 3.3V, 5V and 12V (12V via VDD pin) and under voltage protection(UVP) monitoring for 3.3V and 5V. When an OV or UV event arose and is detected, the power good output (PGO) goes low and the FPO will be set to high. The protection latch can be reset by setting PSON to high. UVP function is enabled 75ms after PSON is set low and de-bounced. Besides, there is a 2.3ms delay with 38ms de-bounce at turn off but no delay during turn on. When OVP and UVP detected the right voltage level, a PGO signal will be issued. DIP-8 SOP-8 FEATURES * Over Voltage Protection and Lock Out for 3V, 5V and 12V. * Under Voltage Protection and Lock Out for 3.3V and 5V. * Open Drain Output for PGO and FPO pin. * 300ms delay for PGO. * 75ms delay for 3.3V and 5V short-circuit turn-on protection. * 2.3ms PSON control to FPO turn-off delay. * 38ms PSON control de-bounce. * 73us width noise deglitches. * Wide supply voltage range from 4V ~15V. ■ ORDERING INFORMATION Ordering Number Lead Free 3510L-D08-T - Halogen Free 3510G-D08-T 3510G-S08-R Package Packing DIP-8 SOP-8 Tube Tape Reel MARKING DIP-8 www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd SOP-8 1 of 8 QW-R502-408.E 3510 CMOS IC PIN CONFIGURATION PIN DESCRIPTION PIN No. 1 2 3 4 5 6 7 8 PIN NAME PGI GND FPO PSON VS33 VS5 VDD PGO TYPE I O I I I I O DESCRIPTION Power good input Ground Fault protection output(invert), open drain output stage ON/OFF control 3.3V over/under-voltage protection 5V over/under-voltage protection Supply voltage/12V over-voltage protection input pin Power good output, open drain output stage UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 8 QW-R502-048.E 3510 CMOS IC BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 8 QW-R502-048.E 3510 CMOS IC ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL VDD RATINGS UNIT 16 V FPO 16 Output Voltage VOUT V PGO 8 All Other Pins -0.3 ~ 16 V DIP-8 1092 Power Dissipation (TA≤25°C) PD mW SOP-8 730 ℃ Operating Temperature TOPR -20 ~ +85 ℃ Storage Temperature TSTG -40 ~ +150 Note: 1.
