Product details
Overview
HIP6601BCBZA from Intersil is a synchronous rectified buck MOSFET driver IC designed to control high-side and low-side N-channel power MOSFETs in core-voltage regulator circuits. It drives the lower gate at 12V (VCC) and the upper gate at 5V–12V (PVCC), supports up to 2MHz switching, delivers 30ns propagation delay, and integrates adaptive shoot-through protection - enabling use in Intel Pentium® III and AMD® Athlon™ microprocessor core supplies.
For engineers reviewing the HIP6601BCBZA datasheet, HIP6601BCBZA pinout, HIP6601BCBZA application, or HIP6601BCBZA equivalent, this page provides verified functional identity, SOIC-8 package mapping, confirmed gate-drive voltage ranges, validated timing parameters, and two technically documented alternative drivers for buck converter design continuity.
Technical Context
The HIP6601BCBZA implements a dual-gate driver architecture with independent upper (UGATE) and lower (LGATE) output stages, where PVCC sets the upper gate drive voltage (5V–12V) while VCC powers the bias circuitry and fixes the lower gate drive at 12V. Its adaptive shoot-through protection monitors LGATE voltage (2.2V threshold) and PHASE node (0.5V threshold) to dynamically sequence turn-off/turn-on delays, preventing simultaneous conduction.
It uses internal bootstrap circuitry requiring only an external BOOT–PHASE capacitor, supports three-state PWM input with 1.4–3.6V shutdown window and 230ns holdoff time, and includes power-on reset with 9.95V rising / 7.6V falling VCC thresholds - all optimized for multi-phase buck controllers like HIP63xx and ISL65xx series.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 12V ±10% - fixed bias rail powering logic, lower gate driver, and internal regulators |
| PVCC Range | 5V to 12V - user-configurable upper gate drive voltage to balance switching vs. conduction losses |
| Max Switching Frequency | 2MHz - enables high-density, low-profile DC/DC converters with fast transient response |
| UGATE Propagation Delay | 30ns - ensures precise timing alignment between PWM input and high-side FET turn-on |
| LGATE Fall Time | 20ns - minimizes dead-time uncertainty and reduces body-diode conduction loss in low-side FET |
| Adaptive Shoot-Through Threshold | LGATE < 2.2V triggers UGATE rise; PHASE < 0.5V enables LGATE rise - hardware-enforced sequencing without external timing components |
| Operating Temp Range | 0°C to +85°C - qualified for commercial-core voltage supply environments |
Pinout & Package
HIP6601BCBZA is housed in an 8-lead narrow-body SOIC package (M8.15 footprint, Pb-free, RoHS compliant) with exposed pad not present - thermal resistance θJA = 97°C/W. Pin functions are electrically and mechanically defined per datasheet FN9072 Rev 9.00.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| UGATE (Pin 1) | Upper gate drive output | Drives high-side N-MOSFET gate; voltage swing referenced to PHASE, amplitude set by PVCC |
| BOOT (Pin 2) | Floating bootstrap supply | Connects to external capacitor charging from PHASE node; enables high-side drive without isolated supply |
| PWM (Pin 3) | Three-state control input | Accepts controller PWM signal; 3.6V rising / 1.45V falling thresholds; 1.4–3.6V window forces shutdown |
| GND (Pin 4) | Bias and reference ground | Common return for VCC, PWM, and internal logic; separate from power ground paths |
| LGATE (Pin 5) | Lower gate drive output | Drives low-side N-MOSFET gate; rail fixed at VCC (12V), sink/source impedance ≤4Ω |
| VCC (Pin 6) | Bias supply input | 12V ±10% input powering internal logic, lower driver, and POR circuitry |
| PVCC (Pin 7) | Upper gate drive supply | Configures UGATE voltage level (5–12V); decoupled via local 0.15µF capacitor |
| PHASE (Pin 8) | Switch-node sensing terminal | Connects to source of high-side / drain of low-side MOSFET; monitored for shoot-through protection and bootstrap recharge |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-MOSFET drive capability | Simultaneously controls high-side and low-side FETs from single PWM input - eliminates need for external level shifters or dual controllers |
| Adaptive shoot-through protection | Hardware-based sequencing using real-time LGATE and PHASE monitoring - no external RC timing networks required |
| Internal bootstrap device | On-chip charge pump circuitry - only external BOOT–PHASE capacitor needed, reducing BOM count and layout complexity |
| Three-state PWM input | 1.4–3.6V shutdown window with 230ns holdoff - enables seamless system-level enable/disable without controller reconfiguration |
| Supply undervoltage lockout (UVLO) | 9.95V VCC rising threshold / 7.6V falling threshold - prevents erratic operation during brown-out or soft-start conditions |
Applications
| Core Voltage Regulation for x86 Microprocessors | High-Frequency Low-Profile DC/DC Converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6609IRZ | Same SOIC-8 package; supports 5–12V dual-rail drive (both UGATE/LGATE); lacks adaptive shoot-through (uses fixed delay) | Requires external dead-time tuning for optimal efficiency; better suited for fixed-frequency designs with known FET characteristics | Select when gate drive symmetry and simplified timing are prioritized over dynamic shoot-through margin. |
| MP8765DJ-LF-P | QFN-16, integrated bootstrap diode; 5–12V dual-rail; 1.5MHz max frequency; no three-state PWM input | Designed for cost-sensitive, medium-power applications; requires different PCB layout and lacks shutdown window functionality | Select when board space is constrained and integrated bootstrap diode simplifies bill-of-materials. |
Compared with ISL6609IRZ and MP8765DJ-LF-P, the HIP6601BCBZA uniquely combines SOIC-8 compatibility, adaptive shoot-through protection, and three-state PWM control - making it irreplaceable in legacy multi-phase CPU VRMs where timing margin and phase-shedding capability are critical.

FAQ
What is the exact gate drive voltage configuration supported by the HIP6601BCBZA?
The HIP6601BCBZA configures the lower gate drive at a fixed 12V (VCC rail), while the upper gate drive voltage is user-selectable from 5V to 12V via the PVCC pin. This dual-rail flexibility allows optimization of switching losses (higher PVCC) versus conduction losses (lower PVCC) in synchronous buck topologies. The HIP6601BCBZA does not support independent lower-rail adjustment - only the HIP6603B variant offers that capability.
Does the HIP6601BCBZA include built-in protection against shoot-through, and how does it work?
Yes, the HIP6601BCBZA integrates adaptive shoot-through protection. It monitors the LGATE voltage and releases UGATE only after LGATE falls below 2.2V; during UGATE turn-off, it monitors PHASE and enables LGATE only after PHASE drops below 0.5V. This hardware-based, dynamic sequencing eliminates fixed-delay timing errors and prevents simultaneous conduction - a key reliability feature confirmed in FN9072 Rev 9.00 Section "Adaptive Shoot-Through Protection".
What package type and footprint does the HIP6601BCBZA use, and is thermal pad soldering required?
The HIP6601BCBZA uses an 8-lead narrow-body SOIC package (M8.15 drawing, Pb-free, RoHS compliant) with no exposed thermal pad. Unlike EPSOIC or QFN variants, the SOIC version has standard gull-wing leads and requires no bottom-side pad soldering. Its thermal resistance is θJA = 97°C/W on a standard test board, and datasheet FN9072 explicitly states "exposed pad not present" for the CCBZ suffix variant.
Can the HIP6601BCBZA be used with a 5V-only supply, or does it require 12V on VCC?
The HIP6601BCBZA requires 12V ±10% on the VCC pin to operate correctly - this is specified in the "Recommended Operating Conditions" table (Page 5, FN9072 Rev 9.00). While PVCC may be set to 5V for upper gate drive, VCC must remain at 12V to power internal logic, lower gate driver, and POR circuitry. Attempting 5V on VCC will prevent initialization and result in no gate drive output.
Is the HIP6601BCBZA still recommended for new designs, and what is its lifecycle status?
No - the HIP6601BCBZA is marked "NOT RECOMMENDED FOR NEW DESIGNS" in the official datasheet (FN9072 Rev 9.00, Page 1). Intersil states "NO RECOMMENDED REPLACEMENT" and directs users to contact Technical Support. However, Aetrix Electronics continues to supply HIP6601BCBZA for legacy system repair, obsolescence mitigation, and production continuity programs with full traceability and extended lifecycle coordination.
