Device Overview
MP26085DJ-LF-Z is a MPS constant-current / constant-voltage controller in a TSOT23-8 package. For substitution or design review, the strongest comparison points are Device Function (constant-current / constant-voltage controller), Input Voltage (7 to 20 V), Reference Voltage (1.223 V).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | constant-current / constant-voltage controller | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Input Voltage | 7 to 20 V | Defines compatibility with the available system input rail and its operating range. |
| Reference Voltage | 1.223 V (1% accuracy) | Defines the output/reference voltage range or setpoint that must match the target rail, battery or threshold. |
| Op Amp Bandwidth | 1 MHz (two ORed-output operational amplifiers) | Defines the control/analog amplifier response speed and therefore loop or signal bandwidth available to the design. |
| Exact Package | TSOT23-8 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Current Generator | integrated enable/disable current generator | Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. |
Power-Management Selection Notes
Device Function is constant-current / constant-voltage controller. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. 7 to 20 V is the stated input voltage value. Defines compatibility with the available system input rail and its operating range.
TSOT23-8 is the stated exact package value. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
For reference voltage, 1.223 V is the approved value. Defines the output/reference voltage range or setpoint that must match the target rail, battery or threshold. Technical condition: 1% accuracy. Op Amp Bandwidth is 1 MHz. Defines the control/analog amplifier response speed and therefore loop or signal bandwidth available to the design. Technical condition: two ORed-output operational amplifiers.
For current generator, integrated enable/disable current generator is the approved value. Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits.
