The BQ20Z80DBTR-V102 is supplied in a 38-TFSOP (0.173", 4.40mm Width) package, also designated as the 38-TSSOP supplier device package. The 38-TSSOP body has an exposed pad on the underside that should be soldered to a PCB thermal land for adequate heat transfer during high-rate charge/discharge cycles.
Protection and monitoring capability
As a battery monitor in the Impedance Track™ series, the BQ20Z80DBTR-V102 integrates gas-gauging with a full set of fault protections: overcurrent, overtemperature, over/under voltage, and short circuit. This means a single IC handles both state-of-charge reporting and safety monitoring for a Lithium Ion/Polymer pack — no separate protector needed. Communication is over the SMBus interface, which is the standard for smart-battery data reporting to a host controller or charger. The monitor reports remaining capacity, voltage, current, and temperature directly in SBS format.
