QUICK START PROCEDURE

Refer to Figure 1 for the proper measurement

equipment setup and jumper settings and follow the

procedure below.

NOTE.

When measuring the input or output voltage ripple, care

must be taken to avoid a long ground lead on the oscilloscope

probe. Measure the input or output voltage ripple by touching the

probe tip directly across the VIN or Vcc and GND terminals. See

Figure 2 for proper scope probe technique.

1. Set PS1 = 12V, PS2 = 3.6V, “VFLOAT” (JP2) to

4.1V. Observe I(VIN) (AM1) and I(BAT) (AM2).

The shunt voltage of the LTC4071 is set to 4.1V,

and the battery voltage is set to 3.6V. The

LTC4071 is only shunting its quiescent current,

≈500nA, so all of the current flowing through R1

is going to charge the battery. (12 -3.6)/499 =

16.8mA.

2. Increase PS2 until HBO LED is lit. Observe

V(BAT) (VM2). The HBO LED will activate when

the battery is nearly fully charged or at ≈ Vfloat –

50mV.

3. Continue to increase PS2, and observe AM1 and

AM2. At the programmed float voltage for the

LTC4071, AM2 will go to 0A. The LTC4071 is

now shunting all of the current flowing through

R1, to ground. The float voltage on the LTC4071

has a tolerance of 1%.

4. Disconnect PS1 and decrease PS2 until Vcc

(VM3) goes to less than 100mV. Observe V(BAT)

(VM2). This is the low battery voltage discon-

nect. When the battery voltage reaches the low

battery disconnect threshold (LBO) (2.7V or

3.2V), an internal switch disconnects BAT from

Vcc. The BAT pin current when disconnected is

less than 0.1nA. However the PCB and other

components may increase the total battery leak-

age to 2~10nA. Measuring this leakage current

requires great care.

5. Increase PS2 by 0.3V. Reconnect PS1 and set to

the same voltage as PS2. Slowly increase PS1
