Nordic Semiconductor releases new nPM1100 IC and nPM1100 EK variants
nPM1100 Power Management IC
Nordic Semiconductor recently added three new product variants to its nPM1100 power management IC product range. Until now, the range has only been available in an ultra-compact 2.1 x 2.1 mm chip-scale package (CSP) form factor. The nPM1100 PMIC now comes in WLCSP and QFN package as well as versions with higher termination voltage. This now results in the following variant options for the nPM1100 product range:
|4.1 or 4.2 V||CAAA||QDAA (new addition)|
|4.25 or 4.35 V||CAAB (new addition)||QDAB (new addition)|
The first new variant comes in a more mainstream 4 x 4 mm QFN component package. QFNs allow for easier and cheaper manufacturing as well as simplified design, development, and verification. QFNs also offer greater thermal and vibration robustness compared to CSPs. The QFN component package is a great option when the product is not defined by extreme size constraints. In this case, CSPs are still an absolute requirement. With the second and third new PMIC variants higher maximum (termination) battery charging voltages (VTERM) are supported, also offered in either a CSP or QFN package. The VTERM option is required to fully charge certain types of lithium-ion cells commonly used in portable wireless products. All Nordic nPM1100 variants require no configuration software to operate as all settings are pin configurable. All new product variants are in volume production and available to order now.
What is termination voltage?
Termination voltage is the maximum voltage a battery should reach during charging. It is used by the battery charger circuit to switch from constant current charging to constant voltage charging and is ultimately used to determine when a battery is fully charged, and so when to stop charging.
