Product details
Overview
UBA2032TS/N2,118 from NXP Semiconductors (formerly Philips) is a high-voltage monolithic full-bridge gate driver IC fabricated in EZ-HV SOI process. It drives four external MOSFETs in full-bridge topology, supports up to 550 V bridge voltage, integrates bootstrap diodes and high-voltage level shifters, and features adaptive non-overlap timing - designed specifically for High Intensity Discharge (HID) lamp commutation in automotive and industrial lighting systems.
For engineers reviewing the UBA2032TS/N2,118 datasheet, UBA2032TS/N2,118 pinout, UBA2032TS/N2,118 application, or UBA2032TS/N2,118 equivalent, this page delivers verified technical context, SSOP28 package mapping, oscillator frequency adjustability (up to 100 kHz internal / 200 kHz external), bridge disable function, and start-up delay control - all critical for HID ballast design validation and layout planning.
Technical Context
The UBA2032TS/N2,118 implements dual-level high-voltage level shifting to drive upper-leg MOSFETs with floating supplies (FSL/FSR), while lower-leg drivers reference PGND. Its adaptive non-overlap circuit senses half-bridge voltage slew rate (5–25 V/µs) to dynamically set minimum 600–1300 ns dead time, eliminating fixed-timing compromises across operating frequencies.
Oscillation mode selection is hardware-configured: internal RC oscillator (kosc = 0.94–1.10) enables 50% duty cycle via ÷2 divider (pin DD = SGND), while external clock input (EXTDR) supports direct or divided operation. Bridge position at startup is predefined when divider is enabled (GHL/GLR HIGH, GLL/GHR LOW), ensuring safe initial state before lamp ignition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Bridge Voltage | 550 V - supports direct connection to HID lamp bus without external HV regulation |
| Oscillator Frequency | Up to 100 kHz (internal) / 200 kHz (external) - sets maximum lamp commutation rate and EMI profile |
| Non-overlap Time | 600–1300 ns (adaptive) - prevents shoot-through by sensing dV/dt on half-bridge nodes |
| Bootstrap Diode VF | 0.8–1.2 V @ 1 mA - integrated diodes reduce BOM count and improve reliability vs discrete solutions |
| Gate Drive Current | 130–180 mA source / 150–200 mA sink - sufficient for driving typical 10–50 nC HID MOSFET gates |
| Logic Supply Range | +LVS to −LVS = 5.75–14 V - allows flexible interface with 5 V or 12 V control logic |
| Disable Threshold | Vref = 1.23–1.35 V - fast, precise shutdown independent of supply rail fluctuations |
Pinout & Package
UBA2032TS/N2,118 is housed in SSOP28 (SOT341-1): plastic shrink small outline package, 28 leads, 5.3 mm body width, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−LVS) | Negative logic supply reference | Establishes ground reference for logic inputs (EXTDR, BD, SU, DD); must be tied to system ground or controlled bias |
| 2 (EXTDR) | External oscillator input | Accepts TTL/CMOS clock signal referenced to −LVS; falling edge triggers bridge commutation when divider disabled |
| 3 (+LVS) | Positive logic supply | Provides 5.75–14 V bias for internal logic; decoupling required if shared with noisy controller |
| 6 (HV) | High-voltage supply input | Directly connects to 550 V lamp bus; powers internal regulators and level shifters without auxiliary supply |
| 9 (VDD) | Internal low-voltage supply | Output of internal regulator; requires 100 nF ceramic capacitor to stabilize gate drive voltage under load |
| 10 (SU) | Start-up delay control | RC-filtered input delays power release until VDD reaches 8.25–9.75 V, preventing weak MOSFET turn-on during cold start |
| 12 (BD) | Bridge disable | Hardwired shutdown: >1.29 V disables all outputs regardless of oscillator or control state |
| 13 (RC) | Oscillator timing | Connects external Rosc/Cosc to set internal frequency; short to SGND disables internal oscillator |
| 14 (SGND) | Signal ground | Reference for logic inputs (BD, SU, DD, EXTDR); separate from PGND to avoid noise coupling into control path |
| 15 (GHL) | Higher left gate driver | Drives gate of upper-left MOSFET referenced to SHL; 15–26 Ω on-resistance ensures fast turn-on |
| 16 (FSL) | Floating supply left | Charged via bootstrap diode; supplies gate drive for GHL; must be decoupled with ≥100 nF capacitor |
| 17 (SHL) | Source of higher left MOSFET | Node connecting GHL output to MOSFET source; defines local ground for high-side driver stage |
| 20 (GLL) | Lower left gate driver | Drives gate of lower-left MOSFET referenced to PGND; matched impedance to GHL for balanced switching |
| 21 (PGND) | Power ground | Return path for load current and lower-leg drivers; must be low-inductance plane adjacent to bridge layout |
| 23 (GLR) | Lower right gate driver | Drives gate of lower-right MOSFET referenced to PGND; synchronized with GLL for complementary half-bridge action |
| 26 (SHR) | Source of higher right MOSFET | Node connecting GHR output to MOSFET source; defines local ground for second high-side driver stage |
| 27 (FSR) | Floating supply right | Charged via bootstrap diode; supplies gate drive for GHR; requires dedicated decoupling capacitor |
| 28 (GHR) | Higher right gate driver | Drives gate of upper-right MOSFET referenced to SHR; completes full-bridge gate drive set |

FAQ
What is the maximum operating frequency of the UBA2032TS/N2,118 in external oscillator mode?
The UBA2032TS/N2,118 supports up to 200 kHz bridge commutation frequency when driven by an external clock on pin EXTDR. This is confirmed in the "Characteristics" table (page 10), where fbridge MAX = 200 kHz applies to external oscillator mode. Internal oscillator mode is limited to 100 kHz maximum. The UBA2032TS/N2,118 achieves this using adaptive non-overlap timing that remains effective across the full frequency range.
Does the UBA2032TS/N2,118 require external bootstrap diodes?
No, the UBA2032TS/N2,118 integrates bootstrap diodes internally - explicitly listed under "Features" (page 2) and verified in the "Characteristics" table (Vdiode = 0.8–1.2 V @ 1 mA, page 10). This eliminates the need for four external diodes typically required in discrete full-bridge gate driver designs, reducing BOM count and improving thermal performance. The UBA2032TS/N2,118 leverages these diodes to charge FSL and FSR capacitors during low-side conduction phases.
How does the adaptive non-overlap function work in the UBA2032TS/N2,118?
The UBA2032TS/N2,118 implements adaptive non-overlap by monitoring the slew rate (dV/dt) of the half-bridge nodes (SHL/SHR) - specified as 5–25 V/µs in the "Characteristics" table (page 10). Internal circuitry detects voltage transitions and dynamically adjusts dead time to ensure minimum 600–1300 ns separation between high-side and low-side turn-off/turn-on events. This eliminates fixed-timing compromises and maintains shoot-through prevention across varying load, temperature, and frequency conditions - a key differentiator of the UBA2032TS/N2,118.
Can the UBA2032TS/N2,118 drive negative-voltage HID lamps?
Yes, the UBA2032TS/N2,118 supports negative lamp voltage operation - explicitly documented in "Application with negative lamp voltage" (Figure 7, page 14). In this configuration, the bridge operates at up to −450 V relative to system ground, with +LVS and HV referenced to the control unit supply. Pin assignments and level-shifting architecture enable safe control even when SHL/SHR swing negative, making the UBA2032TS/N2,118 suitable for sodium-migration-minimizing lamp topologies. This capability is intrinsic to the UBA2032TS/N2,118's EZ-HV SOI process and high-voltage level shifter design.
What is the purpose of the divider disable (DD) pin on the UBA2032TS/N2,118?
The DD pin on the UBA2032TS/N2,118 controls activation of the internal ÷2 oscillator divider. When DD = LOW (connected to SGND), the divider is enabled, halving the oscillator frequency to produce exact 50% duty cycle at the bridge outputs - essential for symmetric HID lamp power delivery. When DD = HIGH, the divider is bypassed, allowing 1:1 frequency mapping from oscillator to bridge. This function is detailed in "Oscillation" (pages 6–7) and confirmed in Table 1 (page 7), where DD state directly determines startup bridge position and duty fidelity. The UBA2032TS/N2,118 relies on this hardware-selectable divider for lamp lifetime optimization.
