Renesas HIP4080AIPZ

Overview

HIP4080AIPZ from Renesas Electronics is a high-frequency, 80V/2.5A peak full-bridge N-channel FET driver IC in 20-lead PDIP package. It integrates input comparator, user-programmable dead-time control via HDEL/LDEL pins, charge-pump and bootstrap biasing for high-side gate drive, and HEN/DIS logic override functions. Designed for voice coil motors, switching power amplifiers, and medium-voltage brush motor control.

For engineers reviewing the HIP4080AIPZ datasheet, HIP4080AIPZ pinout, HIP4080AIPZ application, or HIP4080AIPZ equivalent, key selection criteria include 55ns typical propagation delay, 1MHz max switching frequency, 80V high-side bus rating, adjustable dead time down to near-zero, and compatibility with 5V–15V logic inputs.

Technical Context

The HIP4080AIPZ implements a dual half-bridge gate driver architecture with independent high- and low-side outputs per leg (AHO/AHS/ALO/ALS and BHO/BHS/BLO/BLS), supported by internal charge pumps and bootstrap supplies clamped at ~12.8V. Its comparator-based control enables hysteresis and PWM modes, while HEN forces freewheeling in bottom FETs and disables top FETs.

Dead-time is set externally via resistors on HDEL (high-side turn-on delay) and LDEL (low-side turn-on delay) pins, each referenced to ~5.1V. Propagation delays are asymmetric: upper turn-on (THPLH) is 70–110ns typ/max, lower turn-on (TLPLH) is 40–70ns, minimizing shoot-through risk without fixed minimum off-time.

FAQ

What is the maximum bus voltage supported by the HIP4080AIPZ?

The HIP4080AIPZ supports a maximum high-side bus voltage of 80VDC at 25°C to 125°C ambient, with transient rating up to –6.0V. This allows direct interfacing with medium-voltage power stages such as 48V battery systems or industrial DC supplies without external level-shifting circuitry. The HIP4080AIPZ maintains reliable operation within this range when bootstrap and charge-pump supplies are properly configured.

How does the HIP4080AIPZ implement dead-time control?

The HIP4080AIPZ uses two dedicated pins-HDEL (Pin 8) and LDEL (Pin 9)-to set independent turn-on delays for high-side and low-side drivers via external resistors to VSS. Each pin references an internal ~5.1V voltage, generating a timing current that defines delay duration. This user-programmable method avoids fixed dead-time compromises and ensures shoot-through prevention across temperature and process variations.

Can the HIP4080AIPZ drive both high-side and low-side N-channel MOSFETs in a full-bridge configuration?

Yes, the HIP4080AIPZ is explicitly designed to drive four N-channel MOSFETs in a full-bridge topology. It integrates bootstrap supplies (AHB/AHS and BHB/BHS) and charge-pump circuitry to generate floating gate drive voltages for the high-side switches, while low-side drivers (ALO/BLO) operate referenced to VSS. This eliminates the need for P-channel devices or isolated supplies.

What is the purpose of the HEN pin on the HIP4080AIPZ?

The HEN (High-side Enable) pin on the HIP4080AIPZ is a logic input that, when driven low, forces AHO and BHO outputs to low state regardless of IN+/IN- comparator status-effectively disabling both high-side MOSFETs and enabling freewheeling through the bottom devices. This feature supports safe braking, fault recovery, and controlled current decay in motor control applications.

Does the HIP4080AIPZ include undervoltage protection, and how does it behave?

Yes, the HIP4080AIPZ includes built-in undervoltage lockout (UVLO) with rising threshold of 8.1–9.4V and falling threshold of 7.6–8.9V, providing 0.25–0.65V hysteresis. When VDD/VCC drops below UV-, all outputs are disabled; operation resumes only after voltage exceeds UV+. This prevents erratic gate drive during power-up, brown-out, or supply instability-ensuring robust behavior in the HIP4080AIPZ.
