Product details
Overview
TEA2208T/1J from NXP Semiconductors is an active bridge rectifier controller IC designed to replace conventional diode bridges in AC-DC power supplies. It directly drives four external high-voltage MOSFETs, eliminates forward conduction losses of diodes, achieves up to 1.4 % efficiency gain at 90 VAC, and integrates X-capacitor discharge (2 mA). It targets boost-type PFC front-end stages in high-efficiency desktop PC, TV, and server power supplies.
For engineers reviewing the TEA2208T/1J datasheet, TEA2208T/1J pinout, TEA2208T/1J application, or TEA2208T/1J equivalent, key selection considerations include its SOI process construction, dual high-side floating supply architecture (VCCHL/VCCHR), undervoltage lockout per driver domain, drain-source overvoltage protection thresholds, and full-wave synchronous drive for THD reduction.
Technical Context
The TEA2208T/1J implements a polarity-sensing control scheme that switches diagonal MOSFET pairs based on mains voltage polarity detected between pins L and R, using ±250 mV zero-crossing comparator thresholds. Its gate drivers deliver rail-to-rail output with 200 mA typical sink/source current and integrated pull-down circuits active during UVLO.
Power is self-supplied from rectified mains (pin VR) via an internal charge pump generating regulated 12 V (Vregd) for gate drivers and 4.8 V (Vstartup) for start-up sequencing. The IC enters X-capacitor discharge mode when VCC drops below Vdisable, sourcing 4 mA from VR to safely bleed stored energy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Efficiency gain | Up to 1.4 % at 90 VAC mains - directly attributable to elimination of diode forward voltage drop losses. |
| Gate drive capability | 200 mA sink/source typical - sufficient to rapidly charge/discharge gate capacitance of discrete 600 V MOSFETs. |
| X-cap discharge current | 4 mA typical - meets IEC 62368-1 safe discharge requirements for Class I equipment. |
| UVLO threshold | 4.2 V typical (VUVLO) with 1.5 V hysteresis - ensures stable gate driver enable/disable sequencing across temperature. |
| High-side floating supply range | −0.4 V to 700 V (VCCHL/VCCHR) - supports operation with 600 V MOSFETs under transient surges. |
| Zero-crossing detection offset | 250 mV typical (Voffset) - enables reliable switching timing even with noisy mains inputs. |
| Thermal resistance (j-a) | 105 K/W (4-layer JEDEC board) - defines maximum power dissipation limit under real PCB conditions. |
Pinout & Package
TEA2208T/1J is housed in a plastic small outline package (SO14) with 14 leads and 3.9 mm body width (SOT108-1), optimized for high-voltage isolation and thermal performance in compact AC-DC layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| L | Left input node | Source connection point for upper-left MOSFET; senses AC phase polarity relative to R. |
| VCCHL | Left high-side floating supply | Provides isolated bias for GATEHL driver; must be charged before high-side activation. |
| GATEHL | Left high-side gate driver output | Drives gate of upper-left MOSFET; disabled if VCCHL < 4.2 V or VDS > VCCHL − 3.5 V. |
| HVS | High-voltage spacer | No electrical connection; provides creepage/clearance isolation between high-voltage domains. |
| GATELL | Left low-side gate driver output | Drives gate of lower-left MOSFET; enabled earlier than high-side during start-up sequence. |
| VCC | Main supply rail | Regulated 12 V output powering logic and low-side drivers; UVLO triggers at 4.2 V. |
| GND | Reference ground | Common return for all low-side circuits and measurement references (pins 1–8, 10–12). |
| GATELR | Right low-side gate driver output | Drives gate of lower-right MOSFET; synchronized with GATELL for full-wave conduction. |
| R | Right input node | Source connection point for upper-right MOSFET; used with L to determine mains polarity. |
| VCCHR | Right high-side floating supply | Provides isolated bias for GATEHR driver; independent of VCCHL for dual-channel operation. |
| GATEHR | Right high-side gate driver output | Drives gate of upper-right MOSFET; protected against overvoltage relative to VCCHR. |
| VR | Rectified mains input | Primary power source for internal supply; also used for X-cap discharge current path. |
Key Features
| Feature | Design Value |
|---|---|
| Self-supply architecture | Draws power directly from VR pin; eliminates need for auxiliary winding or external bias supply. |
| Integrated X-cap discharge | 2 mA minimum current sourced from VR during power-off; satisfies safety standards without external circuitry. |
| Dual independent high-side supplies | Separate VCCHL and VCCHR pins enable asymmetric MOSFET configurations and reduce cross-talk risk. |
| Full-wave synchronous drive | Simultaneous conduction of two diagonally opposite MOSFETs reduces THD versus half-wave topologies. |
| Start-up sequencing control | Low-side drivers activate first; high-side drivers enable only after VCCHL/VCCHR reach UVLO threshold. |
| Drain-source overvoltage protection | Disables affected gate driver if VDS exceeds VCCHL − 3.5 V (left) or VCCHR − 3.5 V (right), preventing avalanche stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar active bridge rectifier controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STNRG011TR | Single high-side supply architecture; no independent VCCHL/VCCHR; 1.5 A peak gate drive. | Targeted at lower-power adapters (<150 W); lacks integrated X-cap discharge. | Prefer TEA2208T/1J for designs requiring dual floating supplies, X-cap discharge, or >200 W output. |

FAQ
What is the primary function of the TEA2208T/1J in an AC-DC power supply?
The TEA2208T/1J serves as an active bridge rectifier controller that replaces traditional diode bridges by synchronously driving four external high-voltage MOSFETs. It senses AC polarity between pins L and R, activates diagonal MOSFET pairs, eliminates diode forward voltage losses, and improves overall efficiency by up to 1.4 % at 90 VAC. Its design enables direct integration with boost-type PFC controllers in high-efficiency power supplies.
How does the TEA2208T/1J handle X-capacitor discharge during power removal?
When mains power is removed and VCC drops below the disable threshold (Vdisable ≈ 4.2 V), the TEA2208T/1J enters X-capacitor discharge mode, sourcing a guaranteed 4 mA current from pin VR. This safely bleeds stored energy from the input X-capacitor within approximately 0.45 seconds (with 2.2 μF supply capacitor), satisfying IEC 62368-1 safety requirements without external components.
What protection features are built into the TEA2208T/1J?
The TEA2208T/1J incorporates multiple hardware protections: undervoltage lockout (UVLO) for both high- and low-side drivers (4.2 V threshold), drain-source overvoltage protection disabling gate outputs if VDS exceeds VCCHL − 3.5 V or VCCHR − 3.5 V, gate pull-down circuits ensuring MOSFETs stay off during low supply, and start-up sequencing that enables low-side drivers before high-side drivers to prevent shoot-through.
Can the TEA2208T/1J operate with different MOSFET voltage ratings?
Yes - the TEA2208T/1J supports external MOSFETs rated up to 700 V, as confirmed by its absolute maximum pin voltage ratings (e.g., VR, L, R, VCCHL, VCCHR all rated to 700 V under transient conditions). Its gate drivers deliver 200 mA typical sink/source current and tolerate floating supply voltages up to 14 V, making it compatible with standard 600 V and 650 V superjunction MOSFETs commonly used in high-efficiency SMPS designs.
What is the significance of the HVS pins (4, 9, 13) on the TEA2208T/1J?
The HVS pins (4, 9, 13) on the TEA2208T/1J are high-voltage spacers with no electrical connection. They serve solely to increase creepage and clearance distances between high-potential nodes (e.g., VR, L, R, VCCHL, VCCHR) and low-potential nodes (e.g., GND, VCC) on the SO14 package. These pins are not to be connected to any trace or plane and are critical for achieving reinforced insulation in safety-certified AC-DC power supplies.
