Analog Devices Inc./Maxim Integrated MAX5063DASA+

Overview

MAX5063DASA+ from Maxim Integrated is a 125V, 2A high-speed half-bridge MOSFET driver with independently controlled high-side (noninverting) and low-side (inverting) outputs, 35ns typical propagation delay, ±3ns matching between drivers, and TTL logic inputs. It drives telecom power converters requiring robust 100V transient margin and fast gate switching of high-voltage MOSFETs.

For engineers reviewing the MAX5063DASA+ datasheet, MAX5063DASA+ pinout, MAX5063DASA+ application, or MAX5063DASA+ equivalent, this page delivers verified electrical specs, thermal package details, real-world timing behavior, and validated alternative options for high-frequency half-bridge designs.

Technical Context

The MAX5063DASA+ implements dual independent gate drivers using BiCMOS process technology to achieve low R_DS(ON) output stages (2.1–4.6Ω), 2A peak source/sink current, and matched propagation delays critical for shoot-through prevention. Its TTL-compatible logic inputs operate up to 15V independent of V_DD, with 0.25V hysteresis and 2.5pF input capacitance.

It integrates an on-chip bootstrap diode (0.91–1.11V forward drop) between V_DD and BST, eliminating external diode requirements. UVLO thresholds are 6.5–8.0V (V_DD) and 6.0–7.8V (V_BST–HS), both with 0.5V hysteresis, ensuring reliable startup under telecom transient conditions.

Key Specifications

Pinout & Package

MAX5063DASA+ is housed in an 8-pin SO package with exposed pad (S8E-14), optimized for thermal dissipation in high-power density telecom applications. The exposed paddle is internally connected to AGND and must be externally soldered to a large ground plane.

FAQ

What is the logic input type for MAX5063DASA+?

MAX5063DASA+ features TTL-compatible logic inputs with VIH = 1.65–2.0V and VIL = 0.8–1.4V, independent of V_DD voltage. This allows direct interface with standard PWM controllers and microcontrollers without level-shifting. The inputs include 0.25V hysteresis to reject noise during transitions, and internal pull-down (IN_H) and pull-up (IN_L) resistors prevent floating states. MAX5063DASA+ does not support CMOS (V_DD/2) inputs-that variant is designated MAX5062DASA+.

Does MAX5063DASA+ include an integrated bootstrap diode?

Yes, MAX5063DASA+ includes a reliable on-chip bootstrap diode between V_DD and BST pins, with a typical forward voltage drop of 0.91–1.11V and 10ns turn-on/turn-off time. This eliminates the need for an external discrete Schottky diode in most applications, reducing BOM count and PCB area. For lower forward voltage requirements, an external Schottky diode can be added in parallel-but MAX5063DASA+ functions fully without it.

What is the maximum operating frequency supported by MAX5063DASA+?

MAX5063DASA+ supports combined switching frequencies up to 1MHz when driving 100nC total gate charge, as confirmed in the MAX5064 datasheet section (applicable to the entire MAX506x family per device family documentation). Its 35ns typical propagation delay, ≤8ns delay matching, and 2A peak drive current enable clean, fast edges into high-capacitance MOSFET gates. Thermal limits in the 8-pin SO-EP package constrain sustained 1MHz operation to moderate ambient temperatures and adequate copper area.

Is MAX5063DASA+ pin-compatible with HIP2100 or HIP2101?

Yes, MAX5063DASA+ is explicitly documented as HIP2100/HIP2101 pin-compatible per the manufacturer's Selector Guide (19-3502, Rev 5). It shares identical 8-pin SO footprint, pin numbering, and functional assignment-including VDD, BST, DH, HS, AGND, IN_H, IN_L, PGND, and DL. This enables drop-in replacement in existing HIP2100/2101-based designs without PCB modification, preserving layout integrity and qualification effort.

What package type is used for MAX5063DASA+ and how should it be thermally managed?

MAX5063DASA+ uses an 8-pin SO package with exposed pad (S8E-14), where the exposed paddle is internally connected to AGND. To ensure reliable operation at full 2A drive current, the exposed pad must be soldered to a large, low-thermal-resistance PCB ground plane. Per JEDEC 51, this configuration provides 1538.5mW continuous power dissipation at +70°C with 19.2mW/°C derating above that temperature. Avoid thermal isolation of the pad or insufficient solder coverage.
