Bypass it with a 0.1 μF capacitor to PGND if BAT 14 14 14 14 14 I there are long inductive leads to battery. Charger enable input. This active low input, if set high, suspends charge CE 16 16 16 16 16 I and places the device in the low-power sleep mode. Do not pull up this input to VTSB. Available on parts with fixed output voltage. Ground or float for single-cell CELLS 13 13 I operation (4.2 V). For two-cell operation (8.4 V) pull up this pin with a resistor to VCC. Charge mode selection: low for precharge as set by ISET2 pin and high CMODE 7 7 I (pull up to VTSB or <7 V) for fast charge as set by ISET1. Output voltage analog feedback adjustment. Connect the output of a FB 13 13 I resistive voltage divider powered from the battery terminals to this node to adjust the output battery voltage regulation. IN 3, 4 3, 4 3, 4 3, 4 3, 4 I Charger input voltage. Charger current set point 1 (fast charge). Use a resistor to ground to set ISET1 8 8 8 8 8 I/O this value. Charge current set point 2 (precharge and termination), set by a resistor connected to ground. A low-level CMODE signal selects the ISET2 charge ISET2 9 9 9 9 9 I/O rate, but if the battery voltage reaches the regulation set point, bqSWITCHER™ changes to voltage regulation regardless of CMODE input. N/C 13 19 19 - No connection. This pin must be left floating in the application. 1 1 1 1 1 O Charge current output inductor connection. Connect a zener TVS diode OUT between OUT pin and PGND pin to clamp the voltage spike to protect the 20 20 20 20 20 O power MOSFETs during abnormal conditions. Power-good status output (open drain). The transistor turns on when a PG 5 5 5 5 5 O valid VCC is detected. It is turned off in the sleep mode. PG can be used to drive a LED or communicate with a host processor. PGND 17,18 17,18 17,18 17,18 17, 18 Power ground input Charge current-sense input. Battery current is sensed via the voltage drop SNS 15 15 15 15 15 I developed on this pin by an external sense resistor in series with the battery pack. A 0.1- μF capacitor to PGND is required. Charge status 1 (open-drain output). When the transistor turns on STAT1 2 2 2 2 2 O indicates charge in process. When it is off and with the condition of STAT2 indicates various charger conditions (See Table 1) Copyright © 2004–2015, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: bq24100 bq24103 bq24103A bq24104 bq24105 bq24108 bq24109 bq24113 bq24113A bq24115 |
