Product details
Overview
UCC27282QDRCTQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive half-bridge gate driver for N-channel MOSFETs in high-side/low-side configuration, featuring ±3-A peak output current, 16-ns typical propagation delay, 12-ns/10-ns rise/fall time (1.8-nF load), and integrated bootstrap diode. It enables high-efficiency DC/DC conversion in electric power steering systems.
For engineers reviewing the UCC27282QDRCTQ1 datasheet, UCC27282QDRCTQ1 pinout, UCC27282QDRCTQ1 application, or UCC27282QDRCTQ1 equivalent, key selection considerations include its 100-V HS voltage rating, input interlock for cross-conduction protection, 5-V UVLO threshold, functional safety documentation support, and DRC package–specific enable/disable functionality.
Technical Context
The UCC27282QDRCTQ1 implements independent TTL/CMOS-compatible inputs with internal interlock logic that forces both HO and LO low during input overlap-preventing shoot-through without adding fixed dead time. Its robust level shifter supports floating high-side operation up to 100 V referenced to VSS, with <1-ns typical delay matching between HO and LO paths.
UVLO is implemented separately on VDD (5.0-V typical rising threshold) and HB–HS (3.7-V typical rising threshold), ensuring safe startup and fault isolation. The integrated bootstrap diode (VF = 0.85 V typ. at 80 mA) eliminates external diode requirements while maintaining <2.5-Ω dynamic resistance for efficient capacitor recharge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | ±3 A - sufficient to rapidly charge/discharge large gate capacitances and minimize Miller plateau transition losses |
| Propagation Delay | 16 ns typ. - enables high-frequency switching (>1 MHz) with tight timing control in synchronous buck topologies |
| Rise/Fall Time | 12 ns / 10 ns (1.8-nF load) - ensures fast edge rates for reduced switching losses in automotive power stages |
| HS Voltage Rating | 100 V DC - supports 48-V and 400-V battery-derived rail architectures in iBSG and OBC applications |
| UVLO Thresholds | VDD: 5.0 V rising / 4.5 V falling; HB–HS: 3.7 V rising / 3.3 V falling - prevents erratic operation during brownout or bootstrap capacitor depletion |
| Input Interlock | Active when HI and LI both high - immediately disables both outputs to eliminate cross-conduction risk without degrading timing performance |
| Enable Function | DRC-package–only; EN pin with 2.0-V enable threshold and 1.21-V disable threshold - allows system-level fault response and standby power reduction to 7 µA |
Pinout & Package
UCC27282QDRCTQ1 is packaged in a 3 mm × 3 mm, 10-pin VSON (DRC) with exposed thermal pad. This RoHS-compliant, leadless package supports high-density automotive PCB layouts and provides low thermal resistance (RθJB = 21.3°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power input | Supplies low-side driver stage; requires 1-µF local decoupling to VSS; UVLO monitored independently |
| HB | Bootstrap supply | Connects to positive terminal of external bootstrap capacitor; integrated diode charges capacitor from VDD |
| HO | High-side output | Drives gate of high-side N-MOSFET; referenced to HS node; withstands –14 V transient on HS |
| HS | High-side source | Switch node connection; referenced to VSS; rated –10 V to +100 V DC; negative swing tolerance improves noise immunity |
| LO | Low-side output | Drives gate of low-side N-MOSFET; referenced to VSS; delivers ±3-A peak current into 1.8-nF load |
| VSS | Ground reference | Common return for VDD, LI, HI, EN; thermal pad must be soldered to IC ground plane for thermal management |
| LI / HI | Independent inputs | TTL/CMOS-compatible; 250-kΩ internal pulldown; tolerate –5 V; interlocked to prevent simultaneous high state |
| EN | Enable control | DRC-only pin; enables driver when >2.0 V; disables outputs and reduces IDD to 7 µA when ≤1.21 V |
| NC | No connect | Pin 2 is unconnected internally; must remain unpopulated or left floating per design guidelines |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +150°C junction operation - meets automotive powertrain thermal requirements |
| Integrated bootstrap diode | VF = 0.85 V typ. at 80 mA; RD = 2.5 Ω max - eliminates discrete diode, saves board space, and reduces BOM cost |
| Input interlock logic | Hardware-enforced shoot-through prevention - no software or external circuitry needed; preserves timing precision |
| Functional Safety-Capable | Documentation available per ISO 26262 - supports ASIL-B system-level safety analysis for EPS and OBC designs |
| Negative voltage tolerance | Inputs and HS rated to –5 V and –14 V respectively - enhances robustness against ground bounce and ESD transients |
| Low disabled current | 7 µA IDD_DIS - enables ultra-low-power sleep modes in vehicle subsystems without compromising wake-up latency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC27289QDRCTQ1 | Same pinout and electrical specs, but adds programmable dead-time control via external resistor; higher quiescent current (12 µA disabled) | Better suited for systems requiring adjustable dead-time tuning without MCU intervention | Select UCC27289QDRCTQ1 only if dead-time configurability is required; otherwise UCC27282QDRCTQ1 offers lower power and identical core performance |
| LM5109BQDGQRQ1 | SOIC-8 package; no integrated bootstrap diode; 2-A peak current; 25-ns propagation delay; no EN pin or interlock | Used in cost-sensitive, lower-frequency (<300 kHz) automotive auxiliary supplies where layout simplicity outweighs timing precision | Choose LM5109BQDGQRQ1 for legacy SOIC-8 compatibility and lower unit cost; accept trade-offs in timing accuracy, protection features, and layout area |
Compared with UCC27282QDRCTQ1, UCC27289QDRCTQ1 adds dead-time flexibility at the cost of higher static power, while LM5109BQDGQRQ1 sacrifices integration, speed, and protection for SOIC-8 compatibility and cost-making UCC27282QDRCTQ1 optimal for new high-efficiency, high-reliability automotive power designs.

FAQ
What is the maximum allowable voltage on the HS pin of the UCC27282QDRCTQ1?
The UCC27282QDRCTQ1 specifies an absolute maximum HS voltage of 100 V DC with respect to VSS. It also tolerates –14 V transients (pulse width <100 ns), supporting robust operation during ground-bounce events in high-dV/dt automotive environments. Exceeding these limits risks permanent damage per Absolute Maximum Ratings.
Does the UCC27282QDRCTQ1 require an external bootstrap diode?
No, the UCC27282QDRCTQ1 integrates a bootstrap diode with 0.85-V typical forward voltage at 80 mA. This eliminates the need for an external diode in most applications, reducing component count, PCB area, and BOM cost-though an external diode may still be used for enhanced reliability in high-temperature or high-stress conditions.
How does the input interlock feature work in the UCC27282QDRCTQ1?
The UCC27282QDRCTQ1's hardware interlock forces both HO and LO low whenever HI and LI are simultaneously high-preventing shoot-through without introducing fixed dead time. Unlike software-based or RC-delayed methods, this logic operates instantaneously and preserves propagation delay matching, enabling minimal dead-time designs for peak efficiency.
Is the EN pin available on all UCC27282QDRCTQ1 package variants?
No-the EN pin is exclusive to the DRC (10-pin VSON) package variant of the UCC27282QDRCTQ1. SOIC-8 (D) and SOIC-8-PP (DDA) packages do not include the EN pin. Designers selecting the DRC package gain system-level enable/disable control and 7-µA disabled current, critical for automotive low-power modes.
What is the purpose of the UVLO on the HB–HS rail in the UCC27282QDRCTQ1?
The HB–HS UVLO (3.7-V rising threshold) monitors bootstrap capacitor health independently of VDD. If HB–HS falls below threshold, only the high-side output (HO) is disabled-preserving low-side operation and enabling graceful fault handling. This prevents high-side shoot-through due to insufficient gate drive voltage while maintaining system observability.
