The HY510N is PC Power Supply Supervisor.

The device provides protection circuits, power good output (PGO), fault protection latch (FPL_N), and a protection detector function (PDON_N) control. It can minimize external components of switching power supply systems in personal computer. The Over Voltage Detector (OVD) monitors 3.3V, 5V, 12V input voltage level. The Under Voltage Detector (UVD) monitors 3.3V, 5V input voltage level. When OVD or UVD detect the fault voltage level, the FPL_N is latched HIGH and PGO go low. The latch can be reset by PDON_N goo HIGH.  […]


1. The Over Voltage Detector (OVD) monitors 3.3V, 5V, 12V input voltage level.
2. The Under Voltage Detector (UVD) monitors 3.3V, 5V input voltage level.
3. Both of the power good output (PGO) and fault protection latch (FPL_N) are Open Drain Output.
4. 75 ms time delay for UVD.
5. 300 ms time delay for PGO.
6. 38 ms for PDON_N input signal De–bounce.
7. 73 us for internal signal De–glitches.
8. 2.4 ms time delay for PDON_N turn-off FPL_N

TLC7701-EP Datasheet PDF – Supply Voltage Supervisor

Part Number: TLC7701-EP


Package: TSSOP, SOIC 8 Pin Type

Manufacturer: Texas Instruments


TLC7701-EP datasheet



The TLC7701-EP family of micropower supply voltage supervisors provide reset control, primarily in microcomputer and microprocessor systems. During power-on, RESET is asserted when VDD reaches 1 V. After minimum VDD(≥ 2 V) is established, the circuit monitors SENSE voltage and keeps the reset outputs active as long as SENSE voltage (VI(SENSE)) remains below the threshold voltage. An internal timer delays return of the output to the inactive state to ensure proper system reset. The delay time (td) is determined by an external capacitor:


• Power-On Reset Generator
• Automatic Reset Generation After Voltage Drop
• Precision Voltage Sensor
• Temperature-Compensated Voltage Reference
• Programmable Delay Time by External Capacitor
• Supply Voltage Range . . . 2 V to 6 V
• Defined RESET Output from VDD≥ 1 V
• Power-Down Control Support for Static RAM With Battery Backup
• Maximum Supply Current of 16 mA
• Power Saving Totem-Pole Outputs
• Controlled Baseline
• One Assembly/Test Site
• One Fabrication Site
• Available in Extended (–40°C/125°C and –55°C/125°C), Temperature Ranges
• Extended Product Life Cycle
• Extended Product-Change Notification
• Product Traceability
