Product details

Overview

MCP73213T-A5JI/MF from Microchip Technology is a dual-cell Li-Ion/Li-Polymer linear battery charge management controller with integrated pass transistor, current sense, input overvoltage protection (13 V), and thermal regulation. It delivers 8.40 V regulated output voltage, supports 130–1100 mA resistor-programmable fast charge current, and operates across –40°C to +85°C for portable media players and ultra-mobile PCs.

For engineers reviewing the MCP73213T-A5JI/MF datasheet, MCP73213T-A5JI/MF pinout, MCP73213T-A5JI/MF application, or MCP73213T-A5JI/MF equivalent, this page provides verified functional specifications, DFN-10 package layout, factory-preset 8.40 V charge voltage with ±0.6% accuracy over –5°C to +55°C, 10% preconditioning, 32-minute precondition timer, and 6-hour elapse safety timer - all confirmed for this exact variant.

Technical Context

The MCP73213T-A5JI/MF implements a three-phase linear charging algorithm: preconditioning (10% of I_REG at V_BAT < 71.5% × V_REG), constant-current fast charge (programmed via R_PROG), and constant-voltage regulation (8.40 V ±0.6%). It integrates thermal regulation to dynamically limit I_REG above 110°C and suspends charging at 150°C die temperature with 10°C hysteresis.

Its input stage includes undervoltage lockout (4.15 V start, 4.05 V stop), 13 V overvoltage protection with 150 mV hysteresis, and automatic power-down when V_DD falls within +50 mV of V_BAT. The STAT pin provides open-drain status signaling with flashing (Type 2) or on/off (Type 1) output per factory configuration.

Key Specifications

Parameter	Value and Actual Design Meaning
Charge Voltage	8.40 V ±0.6% over –5°C to +55°C - ensures safe, full-capacity charging of 2-cell Li-ion packs without overvoltage risk.
Input OVP Threshold	13.0 V ±0.2 V - protects against wall-adapter spikes and enables use in cost-sensitive AC-DC environments.
Fast Charge Current	130–1100 mA via single R_PROG - supports flexible design for 500–1200 mAh batteries while maintaining thermal control.
Preconditioning	Enabled at 10% of I_REG, threshold = 71.5% × V_REG - safely recovers deeply depleted cells before fast charge initiation.
Elapse Safety Timer	6 hours - prevents indefinite charging under fault conditions; factory-set and non-adjustable for this variant.
Thermal Regulation	Active above 110°C, shutdown at 150°C ±0°C - maintains reliability during high-ambient or high-power operation.
Package	DFN-10 (3 mm × 3 mm) with exposed thermal pad - enables compact PCB layout and efficient heat dissipation in space-constrained devices.

Pinout & Package

Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP) for enhanced thermal performance. Pin 11 (EP) must be soldered to PCB copper pour with multiple vias for optimal heat transfer.

Pin/Terminal	Circuit Role	Design Meaning
VDD (Pins 1, 2)	Battery management input supply	Accepts 4.2–13 V input; 18 V absolute max; internal UVLO (4.15 V) and OVP (13 V) protect system.
VBAT (Pins 3, 4)	Battery charge control output	Drain of internal P-MOSFET; connects directly to 2-cell Li-ion (+) terminal; bypass with ≥1 μF capacitor.
NC (Pins 5, 6)	No connection	Unbonded pins; must remain floating - no routing or grounding permitted.
STAT (Pin 7)	Status output	Open-drain logic output; indicates charge state (low = active, high-Z = complete/fault); supports LED or MCU interface.
VSS (Pins 8, 9)	0 V reference	Common ground for battery negative, input supply return, and bypass capacitors - low-impedance star point required.
PROG (Pin 10)	Current regulation & enable	Resistor-to-VSS sets I_REG; >200 kΩ impedance places device in standby - eliminates external enable circuitry.
EP (Pin 11)	Exposed thermal pad	Internally connected to VSS; must be soldered to PCB thermal plane with ≥4 vias for θ_JA = 62°C/W performance.

Key Features

Feature	Design Value
Integrated pass transistor	350 mΩ R_DS(on) at 105°C - reduces external component count and PCB footprint vs. discrete MOSFET solutions.
Factory preset 8.40 V regulation	±0.6% accuracy over –5°C to +55°C - eliminates need for external voltage-divider trimming in production.
Automatic recharge at 95% V_REG	Reinitiates charge when battery self-discharge drops voltage below 8.0 V - extends runtime in always-on portable devices.
Soft-start circuitry	Controls inrush current during V_DD application - prevents input rail collapse and stabilizes startup in low-impedance adapter systems.
Battery short protection	Detects V_BAT < 3.4 V and limits current to 25 mA - safeguards against damaged or shorted cells during insertion.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-cell Li-ion linear charge management applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP73213-A6S/MF	Identical 8.40 V regulation, 13 V OVP, 10% preconditioning, and 6 hr elapse timer - same factory preset configuration.	No functional difference; both support Type 1 (on/off) STAT output and 95% automatic recharge threshold.	Select MCP73213T-A5JI/MF for tape-and-reel packaging; MCP73213-A6S/MF for different reel size or lot traceability requirements.
BQ24075RGTR	Single-cell only (4.2 V), no 8.4 V option; lacks integrated OVP; requires external MOSFET for reverse discharge protection.	Not suitable for dual-cell systems; requires redesign of voltage feedback network and protection circuitry.	Only consider if migrating to single-cell architecture; otherwise, MCP73213T-A5JI/MF provides direct dual-cell functionality with no layout changes.

Compared with MCP73213-A6S/MF, the MCP73213T-A5JI/MF offers identical electrical behavior and pinout but differs in packaging format and date code marking; compared with BQ24075RGTR, it delivers native dual-cell support, integrated 13 V OVP, and factory-trimmed 8.40 V regulation - eliminating four external components and reducing validation effort.

FAQ

What is the factory-preset charge voltage for MCP73213T-A5JI/MF?

The MCP73213T-A5JI/MF is factory preset to 8.40 V nominal charge voltage with ±0.6% regulation accuracy over –5°C to +55°C ambient temperature. This value is laser-trimmed during manufacturing and cannot be adjusted externally - ensuring consistent dual-cell Li-ion charging without calibration.

Does MCP73213T-A5JI/MF include input overvoltage protection?

Yes, MCP73213T-A5JI/MF includes integrated input overvoltage protection triggered at 13.0 V ±0.2 V. When V_DD exceeds this threshold, the device enters shutdown mode, disables charging, and pulls STAT high-impedance - protecting downstream circuitry from wall-adapter surges and plug/unplug transients.

How is fast charge current programmed on MCP73213T-A5JI/MF?

Fast charge current on MCP73213T-A5JI/MF is set by connecting a single resistor (R_PROG) from PROG (Pin 10) to VSS. For example, a 1.1 kΩ resistor yields ~1000 mA, while a 10 kΩ resistor yields ~130 mA. The relationship follows I_REG = 1104 / R_PROG (mA, R_PROG in kΩ), with tolerance maintained across –5°C to +55°C.

What happens when the battery voltage drops after full charge completion?

When V_BAT drops to 95% of V_REG (i.e., 8.0 V for MCP73213T-A5JI/MF), the device automatically reinitiates charging. This 95% threshold is factory fixed and enables maintenance charging in always-on devices like portable media players without requiring host MCU intervention.

What thermal protection features does MCP73213T-A5JI/MF provide?

MCP73213T-A5JI/MF provides two-tier thermal protection: dynamic thermal regulation begins above 110°C to reduce I_REG and prevent overheating, and hard thermal shutdown activates at 150°C ±0°C. Charging resumes only after die temperature falls below 140°C - safeguarding both IC reliability and battery safety during sustained high-power operation.
