PINI/O(1)DESCRIPTION
NAMENO.
INA2PDC 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.
SYSB2PRegulated 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.
BATC2PBattery Connection. Connect to the positive terminal of the battery. Bypass BAT to GND with at least 1 µF of ceramic capacitance.
GNDD2-Ground connection. Connect to the ground plane of the circuit.
SCLB1I/OI²C Interface Clock. Connect SCL to the logic rail through a 10-kΩ pullup resistor.
SDAC1I/OI²C Interface Data. Connect SDA to the logic rail through a 10-kΩ pullup resistor.
/INTA1OINT 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/MRD1I/OManual Reset Input/ NTC thermistor pin. TS/MR is a general purpose input that must be held low for greater than tLPRESS to go into Ship mode or perform a hardware reset. It can also be used to detect shorter button press durations such as tWAKE1 and tWAKE2. TS/MR 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.
