Product details
Overview
TEA2093TS/1Z from NXP Semiconductors is a GreenChip synchronous rectifier (SR) controller IC for secondary-side flyback and asymmetrical half-bridge converters. It delivers adaptive gate drive, 37 mV regulation voltage, 0.50 A source / 0.65 A sink gate drive capability, and operates with output voltages down to 0 V - enabling high-efficiency USB PD and quick-charge adapters.
For engineers reviewing the TEA2093TS/1Z datasheet, TEA2093TS/1Z pinout, TEA2093TS/1Z application, or TEA2093TS/1Z equivalent, key selection considerations include drain-sense voltage tolerance (up to 120 V), self-supply capability for low-VOUT and high-side rectification, UVLO with active gate pull-down, and TSOP6 package compatibility with space-constrained AC/DC designs.
Technical Context
The TEA2093TS/1Z implements a drain-source differential sensing architecture to regulate SR MOSFET conduction via real-time VDS monitoring, maintaining −37 mV regulation level during on-state and triggering fast turn-off at zero-current crossing. Its SOI process enables robust operation under high dI/dt conditions.
It supports dual supply modes: self-powered via CAP pin charging from DRAIN (for <4.7 V outputs or high-side rectification), or externally powered via XV pin (enabling 4 V to 12 V gate drive scaling). Gate driver output is actively pulled low during UVLO (CAP < 3.6 V) and post-turn-off (drain > 300 mV), with 6.8 Ω typical pull-down resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Regulation voltage | −37 mV typical; sets precise VDS threshold for stable SR MOSFET on-state control |
| Gate drive source/sink | 0.50 A / 0.65 A typical; ensures fast switching of standard and logic-level SR MOSFETs |
| Drain sense voltage range | −0.8 V to +120 V; accommodates high-voltage flyback secondary waveforms without clamping |
| UVLO start/stop | 3.70 V / 3.60 V typical on CAP pin; guarantees reliable startup and shutdown with active gate pull-down |

| Max gate voltage | 12.3 V typical (XV ≥18 V); drives standard MOSFETs to minimum RDS(on); drops to 4.2 V at 5 V XV for logic-level devices |
| Switch-off detection | 300 mV typical drain overvoltage; triggers 7 Ω gate pull-down to prevent shoot-through |
Pinout & Package
TEA2093TS/1Z is housed in a TSOP6 (SOT457) plastic surface-mounted package: 6-pin, 3.1 mm × 2.7 mm footprint, 1.1 mm max height, with gull-wing leads optimized for automated assembly and thermal performance (Rth(j-a) = 200 K/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| GND | Ground reference | Common return for all internal circuits and gate driver sink path |
| XV | External supply input | Selects gate drive voltage: 4 V (logic-level) or 9–12 V (standard MOSFETs) based on connection |
| GATE | SR MOSFET gate driver output | Delivers up to 0.65 A sink current; actively pulled low during UVLO and post-turn-off |
| SOURCE | SR MOSFET source sense input | Enables Kelvin sensing to reject PCB track IR drop errors during high-dI/dt conduction |
| DRAIN | SR MOSFET drain sense input | Accepts up to +120 V; initiates gate drive on negative VDS and triggers turn-off at +300 mV |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous rectifier controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NCP4306DR2G | Fixed 5 V gate drive; no self-supply mode; requires external bias; 40 mV regulation voltage | Limited to low-VOUT applications only when paired with auxiliary winding; not suitable for high-side or 0 V start-up | Choose for cost-sensitive, fixed-output adapters where auxiliary winding is acceptable and self-supply is unnecessary |
| Infineon IRS11682PBF | Higher 150 V drain rating; integrated bootstrap diode; 35 mV regulation; no XV pin for gate voltage selection | Requires external bootstrap capacitor; less flexible gate voltage tuning; better suited for higher-power (>100 W) designs | Choose for high-voltage, high-power flyback supplies needing extended drain tolerance and simplified gate drive path |
Compared with NCP4306DR2G and IRS11682PBF, TEA2093TS/1Z uniquely combines self-supply capability, adjustable gate voltage (4–12 V), and −37 mV precision regulation - making it optimal for compact, multi-protocol USB PD adapters and low-VOUT battery chargers where auxiliary winding elimination and wide output range are critical.

FAQ
What is the function of the XV pin on the TEA2093TS/1Z?
The XV pin on the TEA2093TS/1Z selects the gate driver output voltage level: grounding XV sets ~9 V drive for standard SR MOSFETs, connecting XV to output (≤4.7 V) enables ~4.2 V drive for logic-level devices, and applying ≥18 V yields up to 12.3 V. This flexibility allows one TEA2093TS/1Z design to support multiple MOSFET types without hardware changes.
How does the TEA2093TS/1Z achieve self-supply for high-side rectification?
The TEA2093TS/1Z achieves self-supply for high-side rectification by charging the external capacitor on the CAP pin through the DRAIN pin during positive drain voltage phases. This eliminates the need for an auxiliary winding or external bias supply, enabling compact, low-component-count high-side SR designs - a capability confirmed in Section 8.2 and Figure 10 of the TEA2093TS/1Z datasheet.
What is the significance of the −37 mV regulation voltage in the TEA2093TS/1Z?
The −37 mV regulation voltage (Vreg(drv)) in the TEA2093TS/1Z defines the target drain-source differential voltage during SR MOSFET conduction. The IC dynamically adjusts gate drive to maintain this precise level, minimizing conduction loss while avoiding false turn-off at light loads - directly contributing to >94% efficiency in USB PD adapters per Section 11 of the TEA2093TS/1Z datasheet.
Can the TEA2093TS/1Z operate with 0 V output voltage?
Yes, the TEA2093TS/1Z is explicitly specified to operate across a 0 V to full-output-voltage range, as stated in Section 2.2 ("Operates in a wide output voltage range down to 0 V"). This enables continuous synchronous rectification during the constant-voltage (CV) phase of Li-ion battery charging, where output voltage approaches cell voltage and traditional controllers may revert to diode mode.
What package type is used for the TEA2093TS/1Z and what are its key mechanical features?
The TEA2093TS/1Z uses the TSOP6 (SOT457) package: a 6-pin, gull-wing surface-mount outline measuring 3.1 mm × 2.7 mm with 0.95 mm lead pitch and 1.1 mm maximum height. Its compact size and JEDEC-standard footprint support high-density PCB layouts, while the SOI fabrication enhances noise immunity in high-dI/dt flyback environments - details confirmed in Sections 4 and 13 of the TEA2093TS/1Z datasheet.
