TL7700 SLVS220G–JULY1999–REVISEDAUGUST2016 www.ti.com 8 Detailed Description 8.1 Overview The TL7700 is a bipolar integrated circuit designed for use as a reset controller in microcomputer and microprocessor systems. The SENSE voltage can be set to any value greater than 0.5 V using two external resistors. The hysteresis value of the sense voltage also can be set by the same resistors. The device includes a precision voltage reference, fast comparator, timing generator, and output driver, so it can generate a power-on resetsignalinadigitalsystem. The TL7700 has an internal 1.5-V temperature-compensated voltage reference from which all function blocks are supplied. Circuit function is very stable, with supply voltage in the 1.8-V to 40-V range. Minimum supply current allowsusewithaclineoperation,portablebatteryoperation,andautomotiveapplications. 8.2 Functional Block Diagram VCC Vs= 500 mVTyp RESET Reference Voltage + + + SENSE − − − ICT(A) High: On R Q S IS(A) GND CT Copyright © 2016,Texas Instruments Incorporated A.

When the capacitor voltage exceeds the threshold level of the output drive comparator, RESET changes from a low to a high level. The output pulse duration is the time between the point when the sense-pin voltage exceeds the threshold level and the point when the RESET output changes from a low level to a high level. When the TL7700 is used for system power-on reset, the output pulse duration, t , must be set longer po thanthepowerrisetime.Thevalueoft is: po t =C ×105seconds po t where • C isthetimingcapacitorinfarads (3) t There is a limit on the device response speed.
