2 / 59 page www.ti.com ORDERING INFORMATION bq2060 SLUS035E – JANUARY 2000 – REVISED OCTOBER 2005 PIN DESCRIPTIONS TERMINAL DESCRIPTION NAME NO. Serial communication input/output. Open-drain bidirectional communications HDQ16 1 port Serial memory clock. Output to clock the data transfer between the bq2060 ESCL 2 and the external nonvolatile configuration memory Serial memory data and address. Bidirectional pin used to transfer address ESDA 3 and data to and from the bq2060 and the external nonvolatile configuration memory Register backup input. Input that provides backup potential to the bq2060 RBI 4 registers during periods of low operating voltage. RBI accepts a storage capacitor or a battery input. Regulator output. Output to control an n-JFET for VCC regulation to the REG 5 bq2060 from the battery potential Supply output. Output that supplies power to the external EEPROM VOUT 6 configuration memory VCC 7 Supply voltage input VSS 8 Ground. DISP 9 Display control input. Input that controls the LED drivers LED1–LED5 10,11,12, LED1-LED5 LED display segment outputs. Outputs that each may drive an external LED 13,14 Discharge FET control output. Output to control the discharge FET in the DFC 15 Li-ion pack protection circuitry Charge FET controll output.
