Product details
Overview
BQ298006RUGR from Texas Instruments is a high-side single-cell Li-ion/Li-polymer battery protector IC with integrated charge-pump NFET drivers, ±12mV overcurrent-in-charge (OCC) threshold, 2.500V undervoltage protection, and 75°C internal overtemperature cutoff. It enables fast/flash charging in space-constrained portable devices using a 1mΩ sense resistor and supports system reset via CTR pin.
For engineers reviewing the BQ298006RUGR datasheet, BQ298006RUGR pinout, BQ298006RUGR application, or BQ298006RUGR equivalent, key selection criteria include its factory-configured 1.00s overvoltage delay, 20ms undervoltage delay, CTR-driven FET override capability, and compatibility with 0V charging only in BQ2980-series variants.
Technical Context
The BQ298006RUGR implements high-side protection using an internal charge pump to drive NFET gates, delivering VGS ≈ VDD × AFETON (1.45–1.81 V/V) across full operating voltage range. Its ±1mV current-sense accuracy supports ultra-low-RSNS (1mΩ) designs without sacrificing precision.
It features dual-mode CTR functionality: active-high override for system reset/shutdown (with 200µs detection and 5.4s shutdown timeout), or configurable PTC-based external overtemperature sensing using factory-set 1.5MΩ/5MΩ/8MΩ internal pull-up resistors.
Key Specifications

|---|---|
| OVP Threshold | 4.475V - Factory-configured overvoltage trip point with 200mV hysteresis for stable recovery |
| UVP Threshold | 2.500V - Undervoltage cutoff enabling low-battery disconnect with 20ms delay |
| OCC Threshold | –12mV - Negative voltage drop across sense resistor triggering CHG FET disable during overcharge |
| OCD Threshold | 14mV - Positive voltage drop across sense resistor triggering DSG FET disable during overdischarge |
| OT Threshold | 75°C - Internal die temperature limit with fixed 4.5s detection delay and 8–22°C hysteresis |
| CTR Function | Active-high input supporting either host-controlled reset (≤3.6s) or shutdown (>5.4s); configurable for PTC OT sensing |
| Supply Current | 4µA normal mode / 0.1µA shutdown - Enables long-term battery storage without significant drain |

Applications
| Smartphones | Tablets |
|---|---|
|
Use Scenario: Primary cell protection in slim-profile smartphones with flash charging and tight thermal budgets.

Use Scenario: Battery safety management in multi-cell parallel configurations where individual cell monitoring is impractical. IC Role / Device Role / Timing Role: Standalone protector enforcing 2.500V UVP with 20ms delay to prevent deep discharge during standby. Use Value: Factory-configured 1.00s OVP delay prevents false trips during transient voltage spikes during fast-charge termination. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar battery protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ298000RUGR | 4.475V OVP, 2.600V UVP, 144ms UVP delay, 85°C OT threshold | Higher UVP threshold and longer delay suit higher-voltage Li-ion cells; 85°C OT better for thermally aggressive environments | Select when system requires tighter UV margin and higher thermal trip point than BQ298006RUGR provides |
| BQ298018RUGR | 4.400V OVP, 2.700V UVP, 48ms OCD delay, 85°C OT threshold | Lower OVP threshold accommodates aging cells; faster OCD response improves short-circuit reaction time | Choose for legacy battery packs with reduced voltage tolerance or applications demanding sub-100µs fault clearance |
Compared with BQ298006RUGR, BQ298000RUGR offers higher undervoltage margin and elevated overtemperature cutoff, while BQ298018RUGR trades OVP headroom for faster overcurrent response-both retain identical pinout, package, and CTR functionality.

FAQ
What is the overvoltage protection threshold and accuracy of the BQ298006RUGR?
The BQ298006RUGR has a factory-configured overvoltage protection (OVP) threshold of 4.475V with ±10mV accuracy at 25°C and ±25mV accuracy across –40°C to +85°C. Its 200mV hysteresis ensures stable release after fault clearance, preventing oscillation near trip point. This specification is confirmed in the Device Comparison Table and Electrical Characteristics section of the SLUSCS3L datasheet.
Does the BQ298006RUGR support 0V charging, and under what conditions?
Yes, the BQ298006RUGR supports 0V charging as part of the BQ2980xx series. It activates when VBAT > 1V, VDD < 1.95V (VDRIVER_SHUT – VDRIVER_SHUT_HYS), and PACK+ voltage exceeds 2V. During this mode, the CHG pin is driven to the PACK voltage instead of the charge-pump output, enabling recharge of deeply depleted cells. This function is disabled in BQ2982xx variants.
How does the CTR pin function in the BQ298006RUGR, and what are its two configuration modes?
The CTR pin in the BQ298006RUGR operates in two mutually exclusive modes: (1) active-high FET override-holding CTR > 1V for >200µs disables CHG/DSG for system reset; holding >5.4s triggers shutdown; or (2) PTC-based external OT sensing-using factory-configured 1.5MΩ/5MΩ/8MΩ internal pull-up to detect rising PTC resistance. Mode selection is fixed at manufacture and cannot be changed in-circuit.
What is the undervoltage protection behavior of the BQ298006RUGR during a fault condition?
The BQ298006RUGR triggers undervoltage protection at 2.500V with a 20ms delay. When enabled, UV_SHUT causes the device to enter shutdown mode, reducing current to 0.1µA and driving CHG to PACK voltage to allow 0V charging if conditions are met. If UV_SHUT is disabled (not applicable to BQ298006RUGR), only DSG turns off and power drops to 2–4µA. The UV release occurs when VBAT rises above 2.700V (2.500V + 200mV hysteresis) or a charger is detected.
What are the absolute maximum ratings for the PACK and CHG pins of the BQ298006RUGR?
The BQ298006RUGR specifies an absolute maximum PACK pin voltage of 24V and CHG pin voltage of 20V. These ratings define safe handling limits-not operational conditions. In normal use, PACK operates up to 20V per Recommended Operating Conditions, and CHG output swings between VSS and VDD × AFETON (max ~8.5V at 5V VDD). Exceeding absolute max ratings risks permanent damage, per Section 6.1 of the SLUSCS3L datasheet.
