Product details

Overview

AUR9807DSGD from Diodes Incorporated is a single-cell Li-ion battery charger IC with integrated Active Power Management (APM), designed for simultaneous system power delivery and battery charging in portable electronics. It supports 6V nominal system output, up to 1.5A programmable charge current via ISET1, 40mΩ BAT-to-OUT power path, and automatic AC/USB source selection - deployed in mobile phones and digital cameras requiring stable dual-path power control.

For engineers reviewing the AUR9807DSGD datasheet, AUR9807DSGD pinout, AUR9807DSGD application, or AUR9807DSGD equivalent, key selection criteria include APM set-point regulation (2.6–3.8V), thermal foldback at 110°C, 6V output voltage version, QFN-4.5×3.5-20 package compatibility, and USB/AC mode configuration via MODE/ISET2 pins.

Technical Context

The AUR9807DSGD implements adaptive power source arbitration between AC adapter and battery using internal MOSFETs Q1 and Q2, with 40mΩ BAT-to-OUT conduction resistance enabling efficient battery-supplement mode. Its APM function dynamically prioritizes system load over charging current when VOUT drops below VAPM-REG, maintaining regulated output by reducing charge current in real time.

Charging control uses dual-stage regulation: constant-current (CC) phase set by ISET1 resistor and VSET (2.4–2.6V), followed by constant-voltage (CV) termination at 4.2V ±0.5% with 10–150mA charge-done detection threshold. Thermal regulation activates at 110°C (TJ(REG)) and shuts down at 150°C (TSHTDWN), while UVLO engages below 2.45V input.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	6V nominal system output (DS variant); regulates only when VIN > 6V + 475mV dropout; drops under heavy load or low input.
Max Charging Current	1.5A (set by ISET1 resistor; halved to 750mA when ISET2 = Low in AC mode).
APM Set Point	VAPM-SET range 2.6–3.8V; scaled by factor 1.139–1.162 to define VAPM-REG threshold for load-priority regulation.
Battery Charge Voltage	4.2V ±0.5% regulation accuracy ensures safe Li-ion full-charge termination without overvoltage risk.
Thermal Regulation	Junction temperature regulation at 110°C (TJ(REG)); shutdown at 150°C prevents thermal damage during sustained high-power operation.
Power Path Resistance	40mΩ BAT-to-OUT resistance minimizes voltage drop and power loss during battery-supplement mode.
Sleep Current	<5μA IBAT(SLP) enables ultra-low quiescent drain during battery-only operation, extending standby time.

Pinout & Package

Package: QFN-4.5×3.5-20 with exposed thermal pad (D package). Pin count: 20. RoHS-compliant green packaging.

Pin/Terminal	Circuit Role	Design Meaning
1 VREF	Internal reference output	3.3V ±5% regulated reference; drives external timing or sensing circuits; no capacitor required but 0.1μF recommended.
2 STAT1 / 3 STAT2	Open-drain status flags	Indicate charge state (precharge, CC, CV, done) and fault conditions; require external pull-up resistors.
4 IN	Main input supply	Accepts 4.35–6.3V input; supports AC adapter or USB; includes 2.45–2.65V UVLO protection.
5,6 BAT	Battery connection	Single bidirectional node for charging (IN→BAT) and discharging (BAT→OUT); integrates 40mΩ power FET path.
7 ISET2	Mode-select input	Configures USB current limit (450mA/90mA) or halves AC charge current; logic-level input with hysteresis.
8 MODE	Power source selector	High = AC adapter mode (no hard current limit); Low = USB mode (450/90mA total current cap).
9 CE	Chip enable	Active-high enable with 4–6ms hold-off time; disables all functions and reduces quiescent current.
10 ISET1	Charge current programming	Voltage input (2.4–2.6V) sets max charge current via KSET factor; determines CC rate and precharge/termination thresholds.
11 SYSOFF	System isolation control	Disables BAT-to-OUT path to prevent battery discharge when system is powered off or in deep sleep.
12 TS	Temperature sense input	Monitors NTC thermistor; triggers thermal shutdown if VTS < 0.5V (high temp) or > 2.5V (low temp).
13 APM	APM set-point input	Analog input setting VAPM-SET (2.6–3.8V); defines minimum system output voltage before APM reduces charge current.
14 TMR	Safety timer programming	External resistor sets charge timeout (0.313–0.414 s/Ω); tying to VREF disables timer.
15–17 OUT	System power output	Three parallel pins deliver regulated system voltage (6V); share current to reduce IR drop and thermal stress.
18 /PG	Power-good flag	Open-drain signal asserted high when VOUT is within regulation; requires external pull-up.
19,20 GND	Ground reference	Dual ground pins minimize noise coupling and improve thermal dissipation via exposed pad connection.

Key Features

Feature	Design Value
Active Power Management (APM)	Maintains system output voltage under load by dynamically reducing charge current - avoids brownout and extends battery cycle life.
Automatic Power Source Selection	Seamlessly switches between AC adapter and battery without external circuitry; detects input presence via VIN(DT) threshold (55–130mV above VBAT).
Thermal Regulation & Shutdown	Two-tier thermal response: foldback at 110°C to sustain operation; shutdown at 150°C for safety - protects IC and battery.
Low-Power Sleep Mode	<5μA BAT pin current during battery-only operation; retains short-circuit detection and fast wake-up on input reappearance.
Programmable Charge Termination	Configurable ITERM (10–150mA) and VTERM (95–270mV) allow precise end-of-charge detection across battery chemistries and aging states.
Integrated Short-Circuit Protection	Detects OUT short in both active and sleep modes; pulls BAT-to-OUT with 10mA source to recover from latch-up without reset.

FAQ

What is the purpose of the APM pin on the AUR9807DSGD?

The APM pin sets the Active Power Management reference voltage (VAPM-SET), which defines the minimum system output voltage before the IC reduces charging current to prioritize system load. It accepts 2.6–3.8V analog input and scales internally by 1.139–1.162 to determine VAPM-REG - enabling precise control over power budget allocation without software intervention.

How does the AUR9807DSGD handle power source transitions between AC adapter and battery?

The AUR9807DSGD automatically selects power sources based on input detection: when VIN exceeds VBAT by 55–130mV, it routes power from IN to OUT and charges the battery; when VIN falls below this threshold, it disconnects IN and powers the system directly from BAT through the 40mΩ path. Transition time is under 50μs, ensuring glitch-free operation.

Can the AUR9807DSGD be used with a 5V-only USB power source?

Yes - configure MODE = Low and ISET2 = High for USB mode, limiting total current to 450mA. The IC regulates system output to 6V only when VIN ≥ 6.3V; with 5V USB input, VOUT follows VIN minus dropout (≈4.5–4.7V), and APM activates earlier to maintain stability under load. Output voltage is not guaranteed at 6V in USB mode.

What happens when the battery voltage drops below the recharge threshold after charge completion?

When VBAT falls below VRCH (VBAT(REG) − 0.125V to −0.075V), the AUR9807DSGD re-enters the precharge phase if VBAT < 2.9V, or resumes fast charge if VBAT ≥ 2.9V. This hysteresis prevents oscillation near full charge and ensures reliable top-up cycling - critical for maintaining runtime in intermittently used portable devices.
