Product details

Overview

TDA21102 from Infineon Technologies is a dual high-speed N-channel MOSFET gate driver IC designed for synchronous half-bridge topologies in multi-phase CPU VRMs. It delivers 4 A peak sink/source current per channel, supports up to 2 MHz switching frequency, and features adjustable high-side gate drive voltage (5–12 V) via the PVCC pin. It integrates bootstrap diodes and adaptive shoot-through protection for reliable operation in motherboard power delivery.

For engineers reviewing the TDA21102 datasheet, TDA21102 pinout, TDA21102 application, or TDA21102 equivalent, key selection considerations include propagation delay (≤35 ns HS turn-on), thermal resistance (R_th-JA = 116.2 K/W), bootstrapped high-side drive capability, and compatibility with standard PWM controllers such as Intersil and Analog Devices parts.

Technical Context

The TDA21102 implements two independent, matched high-side/low-side driver channels with integrated bootstrap diodes and adaptive dead-time control to prevent cross-conduction. Each channel features separate PVCC-adjustable gate drive voltage and dedicated PHASE/BOOT/GATEHS/GATELS terminals for precise half-bridge node control.

It operates across a 10.8–13.2 V VCC range and 5–13.2 V PVCC range, with under-voltage lockout thresholds at 9.7 V (rising) and 7.6 V (falling). The device sustains 25 V DC phase-node voltage rating and supports pulse-mode phase-node transients up to ±30 V (500 ns, 2% duty).

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	10.8–13.2 V - ensures stable operation in 12 V rail-based VRM systems
PVCC Adjustment	5–13.2 V - enables optimization of high-side gate drive voltage for ON-resistance vs. switching loss trade-off
Peak Output Current	±4 A - drives high-Q_g MOSFETs with fast edge rates and low switching losses
Max Switching Frequency	2 MHz - supports high-density, high-efficiency multi-phase CPU power stages
Propagation Delay (HS)	18–35 ns - minimizes timing skew between PWM input and gate output for tight phase alignment

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual high-side/low-side gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR2110PbF	Higher propagation delay (60–120 ns), no integrated bootstrap diode, fixed 10–20 V gate drive	Lacks PVCC adjustability and adaptive shoot-through protection; requires external bootstrap diodes	Lower cost but increases BOM and layout complexity; suitable for lower-frequency (<500 kHz), non-critical applications
LM5113MMX/NOPB	Single-channel, higher peak current (5 A), no integrated bootstrap diode, 100 V phase rating	Requires two units per dual-phase design; lacks PVCC adjustment and three-state shutdown	Better for ultra-high-voltage (>60 V) or single-channel optimized designs; not drop-in compatible

Compared with IR2110PbF and LM5113MMX/NOPB, the TDA21102 provides tighter timing control, reduced component count via integrated bootstrap diodes, and flexible gate drive voltage tuning-making it optimal for high-frequency, space-constrained multi-phase VRMs where efficiency and layout simplicity are critical.

FAQ

What is the maximum allowable voltage on the PHASE pin during pulsed operation?

The PHASE pin supports up to +30 V or −20 V for pulses ≤500 ns with ≤2% duty cycle, as specified in the Absolute Maximum Ratings table. This enables safe operation during high-dV/dt switching transitions in synchronous buck topologies without clamping or snubbing circuits.

Does the TDA21102 require external bootstrap diodes?

No. The TDA21102 integrates bootstrap diodes for both high-side channels, eliminating the need for external diodes. This reduces component count, PCB area, and potential failure points in multi-phase VRM designs while maintaining reliable bootstrap capacitor charging.

How does the PVCC pin affect gate drive performance?

The PVCC pin sets the high-side gate drive voltage level between 5 V and 13.2 V. A higher PVCC reduces R_DS(on) conduction loss in the high-side MOSFET but increases gate charge loss; adjusting it allows system-level optimization of total power loss in high-frequency applications.

Can the TDA21102 be used in single-phase configurations?

Yes. Either channel (PWM1/GATEHS1/GATELS1/PHASE1/BOOT1 or PWM2/GATEHS2/GATELS2/PHASE2/BOOT2) can be used independently in single-phase half-bridge applications. Unused pins should be left unconnected or tied according to layout best practices for noise immunity and thermal management.
