MONOLITHIC POWER SYSTEMS (MPS) MP2702GRP-0000-P Battery Charger, LiFePO4, Li-Ion, Li-Pol, NiMH Battery, 6 Cell, 26 V Input, 1 A, QFN-10

MP2702GRP-0000-P is a linear charger for 1-cell to 2- cell Li-ion, Li-polymer, and LiFePO4, and 2-cell to 6-cell NiMH batteries. The device can sustain a voltage up to 26V. The MP2702 measures the battery voltage (VBATT) and automatically charges the battery in four phases: trickle charge, pre-charge, constant-current (CC) fast charge, and constant-voltage charge. The MP2702 provides a dedicated ISET pin to set the charge current by connecting a resistor between ISET and ground. The device also provides a USBM pin to set the input current limit (IIN-LIM) prior to setting the charge current. If the input power is overloaded, the MP2702 has a minimum input voltage limit (VIN-LIM) to reduce battery current. The MP2702 has robust protection features including input and battery over-voltage protection (OVP), a charge safety timer, and battery temperature protection compliant with the JEITA standard. Application includes headphones, wearable devices, emergency calls.

• Trickle charge current is 1A min (minimum clamp, battery charger (TA = 0°C to 70°C))
• ISET pin short-circuit protection (SCP)
• Additional input current limit (IIN-LIM) setting
• Configurable pre-charge current, configurable termination current threshold
• One-time programmable memory selection for three levels of the minimum input voltage limit
• OTP selection for battery-full voltage from 2.4V to 4.5V per cell
• 0.5% battery regulation voltage accuracy, OTP selection for 1-cell or 2-cell battery
• Integrated chip junction temperature (TJ) regulation
• Battery temperature protection compliant with JEITA standard
• QFN-10 package, operating junction temperature range from -40°C to +125°C
