2
The TPS3619 and TPS3620 families of supervisory
circuits monitor and control processor activity by
providing backup-battery switchover for data retention
of CMOS RAM.
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 VIT. When the
supply voltage drops below VIT, the output becomes
active (low) again.
The product spectrum is designed for supply voltages
of 3.3 V and 5 V. The TPS3619 and TPS3620 are
available in an 8-pin MSOP package and are
characterized for operation over a temperature range
of –40°C to +85°C.

SLVS387H – APRIL 2001 – REVISED DECEMBER 2007
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

SLVS387H – APRIL 2001 – REVISED DECEMBER 2007
DETAILED DESCRIPTION
Battery Freshness Seal (TPS3619)
The battery freshness seal of the TPS3619 family disconnects the backup-battery from internal circuitry until it is
needed. This function prevents the backup-battery from being discharged unitl the final product is put to use. The
following steps explain how to enable the freshness seal mode.
1. Connect VBAT (VBAT > VBAT min)
2. Ground PFO
3. Connect PFI to VDD (PFI = VDD)
4. Connect VDD to power supply (VDD > VIT) and keep connected for 5 ms < t < 35 ms
The battery freshness seal mode is automatically removed by the positive-going edge of RESET when VDD is
applied.
Power-Fail Comparator (PFI and PFO)
An additional comparator is provided to monitor voltages other than the nominal supply voltage. The
power-fail-input (PFI) is compared with an internal voltage reference of 1.15 V. If the input voltage falls below the
power-fail threshold VIT(PFI) of typical 1.15 V, the power-fail output (PFO) goes low. If VIT(PFI) goes above V(PFI),
plus about 12-mV hysteresis, the output returns to high. By connecting two external resistors, it is possible to
supervise any voltages above V(PFI). The sum of both resistors should be about 1 MΩ, to minimize power
consumption and also to assure that the current in the PFI pin can be ignored compared with the current through
the resistor network. The tolerance of the external resistors should be not more than 1% to ensure minimal
variation of sensed voltage. If the power-fail comparator is unused, PFI should be connected to ground and PFO
left unconnected.
Backup-Battery Switchover
In case of a brownout or power failure, it may be necessary to preserve the contents of RAM. 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., a 3.6-V lithium cell) 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 until 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 marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
