11 Push Button

Push button’s connecting is shown in Fig 5. IP5305T can identify long push and short push.

⚫

If button is pushed longer than 30ms but shorter than 2s, IP5305T will identify the action as

short push. Short push will open SOC indicator LEDs and step-up converter

⚫

If button is pushed longer than 2s, IP5305T will identify the action as long push. Long push will

close step-up convertor, SOC indicator LED and flashlight LED.

⚫

If button is pushed shorter than 30ms, IP5305T will ignore the action.

⚫

If two short push is detected within 1s, IP5305T will open or close flashlight LED

12 IP5305T battery type selection

IP5305T supports 4.2V, 4.3V, 4.35V, 4.4V battery types.Select the corresponding battery type by

pulling down different resistance values on LED1 (pin 2) of IP5305T, which is multiplexed with LED

display output, as shown in Figure 3 (in all light modes, different pull-down resistors can be connected

through LED1) To select the battery type):

13 IP5305T battery platform selection

IP5305T can select different battery power display thresholds by pulling down resistors

(RVTHS) with different resistance values on LED2 (pin 3) (only valid when 4 power indicator

lights). The connection is shown in Figure 3.

The following table lists the relationship between the power indicator status and the battery

voltage when the resistance of different RVTHS is different. It should be noted that the turn-on voltage

(OCV) in the table is not the actual battery voltage, but after the battery internal resistance

compensation is calculated. The voltage is calculated as follows:

When charging, the turn-on voltage (OCV) = the actual battery voltage (the voltage to ground on

the P5305TBAT (pin 6))-IBAT (the battery-side charging current measured by IP5305T) * RSET (the

cell charging compensation resistor set by IP5305T); During discharge, the turn-on voltage (OCV) =

the actual battery voltage (the voltage to ground on the P5305TBAT (pin 6)) + IBAT (the battery
