ZHCSKP6A January 2020 – February 2022 BQ25616
PRODUCTION DATA
The BQ25616/616J is a standalone device without host control. Any change on CE, ICHG and ILIM pins will cause a real time internal reference change. Charging is enabled or disabled via the CE pin. D+/D– and ILIM pins control the input current limit settings. D+/D– detection and VSET pin setting only takes effect upon adapter plug-in.
Charge current must be programmed to a value within a range of 300 mA to 3000 mA with a pull-down resistor on the ICHG pin. The charge current is set as:
Input current limit must be programmed to a value within a range of 500 mA to 3200 mA with a pull-down resistor on the ILIM pin. The input current limit is set as:
The battery regulation voltage is programmed with a pull-down resistor on the VSET pin as follows:
| BQ25616/616J | |
|---|---|
| USB OTG | 5 V/1.2 A |
| USB Detection | D+/D– |
| VINDPM | 4.3 V and VBAT + 200 mV |
| VBUS Operating Range | 4 V - 13.5 V |
| VREG | VSET pin (4.20 V, 4.35 V, or 4.10 V) |
| Safety Timer | 10 hr fast charge |
| Pre-charge Timer | 2 hr |
| IPRECHG | 5% of ICHG |
| ITERM | 5% of ICHG |
| Charging Temperature Profile | JEITA 0-60°C (BQ25616J), Hot/Cold 0-45°C (BQ25616) |
| OTG Temperature Profile | –20°C to +60°C |
If a fault is detected, the STAT pin will blink at 1 Hz. STAT pin will stop blinking when the fault goes away. All faults will be reset upon adapter re-connection. A boost mode fault will be cleared either by adapter re-connection or toggling of the OTG pin.
