PIN bq24160/3 bq24161/8 I/O DESCRIPTION NAME YFF RGE YFF RGE BAT G1-G4 11, 12 G1-G4 11, 12 I/O Battery Connection – Connect to the positive terminal of the battery. Additionally, bypass BAT to GND with at least a 1 μF capacitor. BGATE F5 10 F5 10 O External Discharge MOSFET Gate Connection – BGATE drives an external P- Channel MOSFET to provide a very low-resistance discharge path. Connect BGATE to the gate of the external MOSFET. BGATE is low during high impedance mode and when no input is connected. BOOT E7 19 E7 19 I High Side MOSFET Gate Driver Supply – Connect a 0.01µF ceramic capacitor (voltage rating > 10V) from BOOT to SW to supply the gate drive for the high side MOSFETs. CD E4 24 E4 24 I IC Hardware Disable Input – Drive CD high to place the bq2416x in high-z mode. Drive CD low for normal operation. Do not leave CD unconnected. D+ E2 2 — — I D+ and D– Connections for USB Input Adapter Detection – When a charge cycle is initiated by the USB input, and a short is detected between D+ and D–, the USB D– E3 1 — — I input current limit is set to 1.5A. If a short is not detected, the USB100 mode is selected. The D+/D– detection has no effect on the IN input. DRV F7 6 F7 6 O Gate Drive Supply – DRV is the bias supply for the gate drive of the internal MOSFETs. Bypass DRV to PGND with a 1 μF ceramic capacitor. DRV may be used to drive external loads up to 10mA. DRV is active whenever the input is connected and VSUPPLY > VUVLO and VSUPPLY > (VBAT + VSLP) IN A1- A4 21 A1- A4 21 I Input power supply – IN is connected to the external DC supply (AC adapter or alternate power source). Bypass IN to PGND with at least a 1 μF ceramic capacitor. INT F6 7 F6 7 O Status Output – INT is an open-drain output that signals charging status and fault interrupts. INT pulls low during charging. INT is high impedance when charging is complete or the charger is disabled. When a fault occurs, a 128 μs pulse is sent out as an interrupt for the host. INT is enabled/disabled using the EN_STAT bit in the control register. Connect INT to a logic rail through a 100k Ω resistor to communicate with the host processor. PGND D1-D7, 5, 15, D1-D7, 5, 15, — Ground terminal – Connect to the thermal pad (for QFN only) and the ground plane of the circuit. E1, G7 16, 17 E1, G7 16, 17 PMIDI B1-B4 20 B1-B4 20 O Reverse Blocking MOSFET and High Side MOSFET Connection Point for High Power Input – Bypass PMIDI to GND with at least a 4.7 μF ceramic capacitor. Use caution when connecting an external load to PMIDI. The PMIDI output is not current limited. Any short on PMIDI will damage the IC. PMIDU B5-B7 23 B5-B7 23 O Reverse Blocking MOSFET and High Side MOSFET Connection Point for USB Input – Bypass PMIDU to GND with at least a 4.7 μF ceramic capacitor. Use caution when connecting an external load to PMIDU. The PMIDU output is not current limited. Any short on PMIDU will damage the IC. PSEL — — E2 2 USB Source Detection Input – Drive PSEL high to indicate that a USB source is connected to the USB input. When PSEL is high, the IC starts up with a 100mA input current limit for USB. Drive PSEL low to indicate that an AC Adapter is connected to the USB input. When PSEL is low, the IC starts up with a 1.5A input current limit for USB. PSEL has no effect on the IN input. Do not leave PSEL unconnected. SCL E6 3 E6 3 I I2C Interface Clock – Connect SCL to the logic rail through a 10k Ω resistor. SDA E5 4 E5 4 I/O I2C Interface Data – Connect SDA to the logic rail through a 10k Ω resistor. STAT G6 8 G6 8 O Status Output – STAT is an open-drain output that signals charging status and fault interrupts. STAT pulls low during charging. STAT is high impedance when charging is complete or the charger is disabled. When a fault occurs, a 128 μs pulse is sent out as an interrupt for the host. STAT is enabled /disabled using the EN_STAT bit in the control register. Pull STAT up to a logic rail thruogh an LED for visual indication or through a 10k Ω resistor to communicate with the host processor. SW C1-C7 18 C1-C7 18 O Inductor Connection – Connect to the switched side of the external inductor. SYS F1-F4 13, 14 F1-F4 13,14 I System Voltage Sense and Charger FET Connection – Connect SYS to the system output at the output bulk capacitors. Bypass SYS locally with at least 10 μF. A 47 μF bypass capacitor is recommended for optimal transient response. 10 Submit Documentation Feedback Copyright © 2011–2012, Texas Instruments Incorporated Product Folder Link(s): bq24160 bq24161 bq24163 bq24168 |
