VBAT RESET SENSE RESET CEOUT ACTUAL SIZE 3,05 mm x 4,98 mm During power on, RESET is asserted when the supply voltage (VDD or VBAT) becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET output active as long as VDD remains below the threshold voltage VIT. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time starts after VDD has risen above the threshold voltage VIT. When the supply voltage drops below the threshold voltage VIT, the output becomes active (low) again. The TPS3613-01 is available in a 10-pin MSOP package and is characterized for operation over a temperature range of –40°C to 85°C. typical operating circuit Address Decoder Power Supply 0.1 µF Monitored Voltage CEIN Rx CEOUT VDD VBAT CE CMOS RAM VCC Address Bus Backup Battery uC SENSE 8 RESET RESET Ry CE CMOS RAM VCC RealTime Clock VCC 8 Data Bus 16 TPS3613 MR Switchover Capacitor Manual Reset VOUT GND 0.1 µF VCC GND Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

If a backup battery is installed at VBAT, the device automatically switches the connected RAM to backup power when VDD fails. In order to allow the backup battery (e.g., 3.6-V lithium cells) to have a higher voltage than VDD, these supervisors do not connect VBAT to VOUT when VBAT is greater than VDD. VBAT only connects to VOUT (through a 15-Ω switch) when VDD falls below VIT and VBAT is greater than VDD. When VDD recovers, switchover is deferred either until VDD crosses VBAT, or when VDD rises above the reset threshold VIT. VOUT connects to VDD through a 1-Ω (max) PMOS switch when VDD crosses the reset threshold.

The TPS3613 use a series transmission gate from CEIN to CEOUT. During normal operation (reset not asserted), the CE transmission gate is enabled and passes all CE transitions. When reset is asserted, this path becomes disabled, preventing erroneous data from corrupting the CMOS RAM. The short CE propagation delay from CEIN to CEOUT enables the TPS3613 device to be used with most processors. The CE transmission gate is disabled and CEIN is high impedance (disable mode) while reset is asserted. During a power-down sequence when VDD crosses the reset threshold, the CE transmission gate is disabled and CEIN immediately becomes high impedance if the voltage at CEIN is high. If CEIN is low when reset is asserted, the CE transmission gate is disabled when CEIN goes high, or 15 µs after reset asserts, whichever occurs first. This allows the current write cycle to complete during power down. When the CE transmission gate is enabled, the impedance of CEIN appears as a resistor in series with the load at CEOUT. The overall device propagation delay through the CE transmission gate depends on VOUT, the source impedance of the drive connected to CEIN, and the load at CEOUT. To achieve minimum propagation delay, the capacitive load at CEOUT should be minimized, and a low-output-impedance driver is used. In the disabled mode, the transmission gate is off and an active pullup connects CEOUT to VOUT. This pullup turns off when the transmission gate is enabled. CEIN t CEOUT 15 µs t RESET t Figure 2.
