XC6190 Series
ETR02031-003
Push Button Reboot Controller
■GENERAL DESCRIPTION
The XC6190 series are timer reset ICs that supply a reboot signal to the system when “L” voltage is input into the
SW1, SW2 pins for a set time (reboot delay time) using two switches (physical buttons).
On type A, the reboot delay time (TDL) can be set as desired by changing the external resistance RT within the range 1s to 20s.
On type B, TDL is fixed internally. When the TS pin is set to “H” level, the delay time is 12.5s. When the TS pin is set to “L”
level, the delay time is 7.5s.
After the reboot signal (TRSTB) is output for 0.4s (TYP), the IC automatically returns to the steady state.
Quiescent current in standby mode is a very small 0.01μA (TYP.), and this contributes to a longer battery drive
time. The small USPN-6 and USPN-6B01 packages enable reduction of mounting space.
The UVLO function is equipped as a protective function to prevent malfunctioning of the IC.

■ OPERATION EXPLANATION
XC6190
Series
The XC6190 series supplies a reboot signal (TRSTB below) to the system by inputting “L” voltage into the SW1, SW2 pins for
the set time (reboot delay time) using two switches (buttons)
On the XC6190AN15xx and XC6190AC15xx, a reboot delay time (TDL below) is set by connecting a resistance (RT below)
to the RT pin.
TDL is determined by the following calculation formula:
RT(kΩ) = { TDL(s) – 0.097 } / 0.062015 * Can be set within the range 1s to 20s.
e.g.) When TDL=12.5s, RT=200kΩ
On the XC6190BN25xx and XC6190BC25xx, TDL is determined by the internal circuitry. When the TS pin is shorted to VIN,
TDL = 12.5s (TYP.), and when the TS pin is shorted to GND, TDL = 7.5s（TYP.).
Even if the TS pin voltage changes from VIN to GND while “L” voltage is input to the SW1 pin and SW2 pin, the value set
prior to the change is maintained.

Details of each circuit part are as follows.

<SW1 pin, SW2 pin>
By inputting “L” voltage into both of these pins during the TDL interval, the reboot signal is output from the RSTB pin.
Both pins are pulled up to VIN by internal resistances, and thus the pin voltage when OPEN is VIN level.
The UVLO circuit is activated by inputting “L” voltage into both the SW1 pin and SW2 pin.
<RT pin: Type A>
RT is connected to this pin to set TDL.
<TS pin: Type B>
This pin is used to set TDL. When the TS pin is shorted to VIN, TDL is set to TDL ＝ 12.5s(TYP.). When the TS pin is shorted
to GND, TDL is set to TDL ＝ 7.5s (TYP.).
Even if the TS pin voltage is changed after “L” voltage is input into both the SW1 and SW2 pins and the internal circuit
starts operation, the value set prior to the change is maintained.
