bq24165 bq24166 bq24167 SLUSAP4B – DECEMBER 2011 – REVISED MARCH 2013 www.ti.com DETAILED DESCRIPTION CHARGE MODE OPERATION Charge Profile Charging is done through the internal battery MOSFET. When the battery voltage is above 3.5V, the system output (SYS) is connected to the battery to maximize the charging efficiency.
PAGE 15
bq24165 bq24166 bq24167 www.ti.com SLUSAP4B – DECEMBER 2011 – REVISED MARCH 2013 BATTERY CHARGING PROCESS Assuming a valid input source has already been attached to IN or USB, as soon as a deeply discharged or shorted battery is attached to the BAT pin, the bq24165/6/7 applies a 50mA current to bring the battery voltage up to acceptable charging levels. During this pre-charge time, the battery FET is linearly regulated to maintain the system output regulation at VSYS(REG).
PAGE 16
bq24165 bq24166 bq24167 SLUSAP4B – DECEMBER 2011 – REVISED MARCH 2013 www.ti.com BATTERY DETECTION When termination conditions are met, a battery detection cycle is started. During battery detection, IDETECT is pulled from VBAT for tDETECT to verify there is a battery. If the battery voltage remains above VDETECT for the full duration of tDETECT, a battery is determined to present and the IC enters “Charge Done”. If VBAT falls below VDETECT, battery detection continues.

Example DPPM Response (VSupply = 5 V, VBAT = 3.1V, 1.5A Input current limit) If the VBAT(REG) threshold is ever less than the battery voltage, the battery FET is turned off and the SYS output is regulated to VSYSREG(FETOFF).

The bq24165/6/7 manages the dual input supply paths as well. The IN input has precedence when valid supplies are connected to both inputs. The two inputs are always isolated from one another. The bq24165/6/7 always seeks to charge from a valid source.

bq24165 bq24166 bq24167 www.ti.com SLUSAP4B – DECEMBER 2011 – REVISED MARCH 2013 LDO OUTPUT (DRV) The bq24165/6/7 contains a linear regulator (DRV) that is used to supply the internal MOSFET drivers and other circuitry. Additionally, DRV supplies up to 10mA external loads to power the STAT LED or the USB transceiver circuitry. The maximum value of the DRV output is 5.45V so it is ideal to protect voltage sensitive USB circuits.

The voltage at TS is monitored to determine that the battery is at a safe temperature during charging. For the bq24166, two temperature thresholds are monitored; the cold battery threshold (TNTC < 0°C) and the hot battery threshold (TNTC > 60°C).

Once the supply drops to VIN_DPM (set by IUSB_ for USB input or VDPM for IN input), the input current limit is reduced down to prevent the further drop of the supply.

The built-in input over-voltage protection to protect the device and other components against damage from overvoltage on the input supply (Voltage from VUSB or VIN to PGND).

The PG output indicates that a valid input source is connected to USB or IN. PG is low when VSUPPLY>VUVLO AND (VBAT+VSLP) < VSUPPLY < VOVP. When there is no supply connected to either input within this range, PG is high impedance. Table 3 illustrates the PG behavior under different conditions.

First, the inductance value should be selected. The bq2416x is designed to work with 1.5µH to 2.2µH inductors. The chosen value will have an effect on efficiency and package size.
