Table 6-1. Pin Functions
| PIN | PIN | I/O (1) | DESCRIPTION |
|---|---|---|---|
| NAME | NO. | I/O (1) | DESCRIPTION |
| IN | A2 | P | DC Input Power Supply. IN is connected to the external DC supply. Bypass IN to GND with at least 1 μF of capacitance using a ceramic capacitor. |
| SYS | B2 | P | Regulated System Output. Connect at least 10-μF ceramic capacitor (at least >1 μF of ceramic capacitance with DC bias derating) from SYS to GND as close to the SYS and GND pins as possible. |
| BAT | C2 | P | Battery Connection. Connect to the positive terminal of the battery. Bypass BAT to GND with at least 1 μF of ceramic capacitance. |
| GND | D2 | - | Ground connection. Connect to the ground plane of the circuit. |
| SCL | B1 | I/O | I 2 C Interface Clock. Connect SCL to the logic rail through a 10-kΩ pullup resistor. |
| SDA | C1 | I/O | I 2 C Interface Data. Connect SDA to the logic rail through a 10-kΩ pullup resistor. |
| /INT | A1 | O | INT is an open-drain output that signals fault interrupts. When a fault occurs, a 128-μs active low pulse is sent out as an interrupt for the host. INT is enabled/disabled using the MASK_INT bit in the control register. Can be pulled up to the logic rail through a 1-kΩ to 20-kΩ resistor. |
| TS/MR | D1 | I/O | Manual Reset Input/ NTC thermistor pin. TS/MR is a general purpose input that must be held low for greater than t LPRESS to go into Ship mode or perform a hardware reset. It can also be used to detect shorter button press durations such as t WAKE1 and t WAKE2 TSMR may be driven by a momentary push-button or a MOS switch. The TSMR pin can also have an NTC thermistor connected on to it. |

Typical Application
A typical application of the BQ25180 consists of the device configured as an I 2 C controlled single cell Li-ion battery charger and power path manager or battery applications such as smart watches and wireless headsets. A battery thermistor may be connected to the TS pin to allow the device to monitor the battery temperature and control charging as desired.
The system designer may connect the TS/MR pin input to a push button to send interrupts to the host as a button is pressed or to allow the application end user to reset the system.
