Device Overview
MP2602DQ-LF-Z is a MPS single-cell linear Li-ion battery charger in a QFN-10 package. For substitution or design review, the strongest comparison points are Device Function (single-cell linear Li-ion battery charger), Input Surge (28 V), Programmable Charge Current (85 mA to 1 A).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | single-cell linear Li-ion battery charger | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Input Surge | 28 V (maximum surge capability) | Defines transient input-voltage tolerance and therefore the margin against short-duration supply overshoot. |
| Programmable Charge Current | 85 mA to 1 A (manufacturer feature range) | Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. |
| Battery Voltage Accuracy | 0.75 % | Defines the electrical voltage envelope that must cover the intended operating or stress level. |
| Standby Current | 90 uA (from VIN) | Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. |
| Exact Package | QFN-10 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
Power-Management Selection Notes
For device function, single-cell linear Li-ion battery charger is the approved value. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. For programmable charge current, 85 mA to 1 A is the approved value. Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. Technical condition: manufacturer feature range.
Exact Package is QFN-10. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
Input Surge is 28 V. Defines transient input-voltage tolerance and therefore the margin against short-duration supply overshoot. Technical condition: maximum surge capability. Battery Voltage Accuracy is 0.75 %. Defines the electrical voltage envelope that must cover the intended operating or stress level.
90 uA is the stated standby current value. Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. Technical condition: from VIN.
