Nexperia NBM5100

Description

The NBM5100A/B is a battery energy management device designed to maximize usable capacity from non-rechargeable, primary batteries when used in lowvoltage,low-power applications requiring burst current loads. The devices overcome voltage drop and battery life limitations associated with extracting high pulse currents (Fig. 1) from lithium primary batteries such as 3.6 V lithium thionyl chloride (Li-SOCl2), which are commonly used in wireless, low-power IoT sensorapplications.

Features

• Programmable constant battery load current: 2 mA to 16 mA
• Protection against battery voltage dips (Brown-out)
• Pulse output current: > 150 mA
• Low ripple regulated programmable output voltage, VDH: 1.8 V to 3.6 V
• Ultra-low standby current: < 50 nA
• Peak conversion efficiency > 90% with adaptive optimization
• Integrated fuel gauge
• Integrated capacitor voltage balancing circuit
• Small 16 pin lead-free package (SOT763-1/DHVQFN16; 2.5 mm × 3.5 mm × 0.85 mm)
• Specified from -40 °C to +85 °C

Typical applications

• temperature, occupancy, e-metering, electronic shelf label, asset tracking, irrigation monitoring
• Bluetooth®, LoRaWAN®, Sigfox™, LTE-M, NB-IoT, Zigbee, etc
• location tags, heart rate monitor, blood glucose meter, remote controls, key fobs
