The suggested circuit is:

GE863-PRO3

VRTC

3V

LithiumF primary

battery ceramic

S-817A19A Seiko

1.2μΑ

10K Ω

F ceramic

The quoted current intensity are without VBATT power supply for the module.

The S-817A19A Seiko LDO has a value of 1.2μA Typ for the quiescent current. Without VBATT power supply voltage, the VRTC Reverse Current is 7- 8 μA Typ. (depending on OSCSEL pin status)

At ambient temperature 20°C, the BR2032 coin type (Panasonic 190 mAh) should be sufficient for 2-3 years with typical current intensity. The CR2032 coin type Panasonic 220 mAh) has an improved behaviour at low and high temperatures.

When the VBATT voltage is present, the VRTC voltage exceeds the S-817 output voltage, so the current from the Lithium Primary Battery is only 1.2μA Typ (or less).

NOTE: the 2-3 years are given considering the worst case (VBATT always off)

5.4 General Design Rules

The principal guidelines for the Power Supply Design embrace three different design steps:

the electrical design

the thermal design

the PCB layout

5.4.1Electrical design Guidelines

The electrical design of the power supply depends strongly from the power source where this power is drained. We will distinguish them into three categories:

+5V input (typically PC internal regulator output)

+12V input (typically automotive)
