부품명 : TL7757CDG4 TL7757CLPRE3 TL7757IDG4
상세내역 : SUPPLY-Voltage SUPERVISOR AND PRECISION Voltage DETECTOR
Texas-Instruments
Texas Instruments

description/ordering information
The TL7757 is a supply-Voltage supervisor designed for use in microcomputer and microprocessor systems. The supervisor monitors the supply Voltage for underVoltage conditions. During power up, when the supply Voltage, VCC, attains a value approaching 1 V, the RESET output becomes active (low) to prevent undefined operation. If the supply Voltage drops below threshold Voltage level (VIT−), the RESET output goes to the active (low) level until the supply underVoltage fault condition is eliminated.

● Power-On Reset Generator
● Automatic Reset Generation After Voltage Drop
● Low Standby Current . . . 20 µA
● RESET Output Defined When VCC Exceeds 1 V
● Precision Threshold Voltage 4.55 V ±120 mV
● High Output Sink Capability . . . 20 mA
● Comparator Hysteresis Prevents Erratic Resets

부품명 : TK65015 TK65015M TK65015MBX TK65015MTL
상세내역 : STEP-UP Voltage CONVERTER WITH Voltage MONITOR
Toko
Toko America Inc

DESCRIPTION

The TK65015 Low Power Step-Up DC-DC converter is designed for portable battery powered systems, capable of operating from a single battery cell down to 0.9 V. The output Voltage is laser-trimmed to 3.0 V. An internal detector monitors the output Voltage and provides an active-low microprocessor reset signal whenever the output Voltage falls below an internally preset limit. An internal underVoltage lockout circuit is utilized to prevent the inductor switch from remaining in the "ON" mode when the battery Voltage is too low to permit normal operation.



FEATURES

■ 0.9 V Operation

■ Very Low Quiescent Current

■ Internal Bandgap Reference

■ High Efficiency

■ Low Output Ripple

■ Microprocessor Reset Output

■ Laser-Trimmed Output Voltage

■ UnderVoltage Lockout

■ Regulation by Pulse Burst Modulation (PBM)



APPLICATIONS

■ Battery Powered Systems

■ Cellular Telephones

■ Pagers

■ Personal Communications Equipment

■ Portable Instrumentation

■ Portable Consumer Equipment

■ Radio Control Systems
