What are the key features of EMB1499QMHE/NOPB?
- Bidirectional current-mode control enables seamless buck/boost conversion for battery charge and discharge in a single-channel IC
- 5.5 V maximum input rating with current-mode PWM control provides fast transient response and cycle-by-cycle overcurrent protection
- 28-pin SOIC package integrates gate drivers and compensation circuitry, reducing external component count in battery management designs
What is EMB1499QMHE/NOPB used for?
EMB1499QMHE/NOPB is designed for bidirectional battery charger and energy storage systems where a single controller must manage both charging from a power source and discharging to a load rail up to 5.5 V. It suits UPS modules, solid-state battery backup circuits, and supercapacitor management systems requiring current-mode control with tight regulation in both power flow directions. The device also serves automotive 12 V to 48 V battery hybridization interfaces and industrial energy harvesting designs needing a compact 28-pin SOIC solution.

Frequently Asked Questions
What control topology does EMB1499QMHE/NOPB use, and over what input voltage range does it operate?
EMB1499QMHE/NOPB uses current-mode PWM control that allows cycle-by-cycle peak current limiting on both the charge and discharge paths, operating from an input voltage up to 5.5 V, which covers 1-cell Li-ion battery rails from 2.5 V to 4.2 V and regulated 5 V bus applications in portable and backup power systems.
How does EMB1499QMHE/NOPB simplify a bidirectional DC/DC converter design compared to using two separate controllers?
EMB1499QMHE/NOPB integrates the gate drive and current sensing for both the forward and reverse power paths in a single 28-pin SOIC, eliminating the need for two separate PWM controllers and their associated bootstrap capacitors, which reduces BOM by approximately 10 to 15 components and shrinks the converter footprint by roughly 30%.
Which energy storage applications favor EMB1499QMHE/NOPB over a unidirectional boost converter?
UPS backup modules, supercapacitor energy buffers, and 48 V mild-hybrid automotive battery systems favor EMB1499QMHE/NOPB because those applications must transfer energy in both directions — charging the storage element during regeneration or grid availability and discharging it to sustain the load — while current-mode control maintains stable regulation across the full 5.5 V input range in both operating modes.
