Product details
Overview
MP26023DQ-LF-P from Monolithic Power Systems is a linear single-cell Li-ion battery charger IC with integrated 28V input surge tolerance, programmable 85mA–1A constant-current charging, ±0.75% battery voltage regulation at 4.2V, and full-charge termination via programmable IBF threshold. It operates in trickle → CC → CV stages and supports USB/adapter input for portable electronics.
For engineers reviewing the MP26023DQ-LF-P datasheet, MP26023DQ-LF-P pinout, MP26023DQ-LF-P application, or MP26023DQ-LF-P equivalent, key selection criteria include input surge rating (28V), thermal shutdown behavior (105–135°C), reverse current blocking (<1µA), NTC-based temperature monitoring (0–50°C range), and soft-start programmability via external capacitor.
Technical Context
The MP26023DQ-LF-P implements a linear charging architecture with dual-stage regulation: constant-current (CC) mode controlled by ISET resistor (RCHG = 1.65–15kΩ), followed by constant-voltage (CV) mode with 0.75% accuracy at 4.2V. Charge termination occurs when current drops to IBF (10–50% of ICHG), set by RBF resistor.
It integrates protection functions including overvoltage lockout (6.0V IN threshold), thermal foldback (sawtooth current waveform above 105°C), and battery reverse current blocking (<1µA). The ACOK and CHG open-drain indicators provide real-time power-good and charge-status signaling to host systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5V–5.5V nominal; survives up to 28V transient surges without damage |
| Charge Current Range | 85mA–1A programmable via RCHG; typical 515mA at RCHG = 3.3kΩ |
| Battery Voltage Accuracy | ±0.75% at 4.2V - ensures safe Li-ion cell voltage control within JEITA limits |
| Reverse Battery Current | <1µA when EN = low - prevents battery discharge into floating input |
| Thermal Shutdown Threshold | 105–135°C with 10°C hysteresis - enables self-limiting operation under high-power dissipation |
| Trickle Charge Threshold | 2.85–3.15V with 230mV hysteresis - initiates preconditioning for deeply discharged cells |

FAQ
What input voltage range does MP26023DQ-LF-P support during normal operation?
The MP26023DQ-LF-P operates normally with 3.5V to 5.5V input, but its internal protection circuitry tolerates transient surges up to 28V without latch-up or damage. Input is automatically disabled if voltage falls below 2.5V or exceeds 6.0V, and the ACOK pin reflects this valid window.
How is charge current programmed, and what resistor values yield 500mA?
Charge current is set by connecting a resistor (RCHG) from ISET (Pin 9) to GND. Per the datasheet, RCHG = 3.3kΩ yields a typical ICHG of 515mA. The relationship is inverse-linear: lower resistance increases current, with 1.65kΩ giving ~1000mA and 15kΩ giving ~100mA.
Does MP26023DQ-LF-P support battery temperature monitoring, and how is it implemented?
Yes - it integrates an NTC thermistor window comparator on Pin 5 (NTC). A 100kΩ NTC (e.g., TH11-4H104F) is connected from NTC to GND, and a 500kΩ pull-up to IN. The IC disables charging if RNTC falls outside 32.3kΩ–376.6kΩ, corresponding to ~0–50°C.
What happens when the device enters thermal protection mode?
Above 105°C, MP26023DQ-LF-P enters thermal foldback: charge current transitions from DC to a sawtooth waveform with reduced average amplitude. This lowers die temperature without halting charge entirely. The frequency and depth are adjustable via the SS pin capacitor.
Can MP26023DQ-LF-P be used without the NTC function?
Yes - the NTC pin must not be left floating. To disable temperature monitoring, replace the NTC thermistor with a fixed 100kΩ resistor from Pin 5 to GND. This satisfies the bias requirement while bypassing thermal cutoff functionality.
What is the purpose of the ACOK pin, and how is it used in system design?
ACOK is an open-drain output that pulls low when VIN is within 2.5V–6.0V, indicating valid adapter/USB input. System microcontrollers use this signal to gate power sequencing, enable charging, or trigger UI feedback - eliminating need for external voltage comparators.
How does the MP26023DQ-LF-P handle deeply discharged batteries?
When battery voltage is below 2.85–3.15V (trickle threshold), the IC initiates preconditioning at 10% of the programmed ICHG. Once VBATT rises above ~3.0V, it transitions to full CC mode - preventing lithium plating and ensuring safe recovery of depleted cells.
