Product details

Overview

ICE1HS01G1XUMA1 from Infineon Technologies is a half-bridge resonant controller IC for LLC topology, featuring 50% duty cycle, 180° phase-shifted dual gate outputs, 380 ns fixed dead time, and programmable minimum switching frequency (25–200 kHz) via external resistor on FMIN pin. It enables zero-voltage switching in AC-DC adapters and LCD/PDP TV power supplies.

For engineers reviewing the ICE1HS01G1XUMA1 datasheet, ICE1HS01G1XUMA1 pinout, ICE1HS01G1XUMA1 application, or ICE1HS01G1XUMA1 equivalent, key selection criteria include its integrated two-level overcurrent protection (frequency shift + latch-off), mains undervoltage sensing with adjustable hysteresis, digital nonlinear softstart, and ±1.5% oscillator accuracy over temperature.

Technical Context

The ICE1HS01G1XUMA1 implements pulse frequency modulation (PFM) for output regulation in LLC resonant converters, using an internal trimmed capacitor (CFS) and externally programmed charge current via FMIN to set f_min. Feedback voltage (0.9–3.9 V) modulates oscillator charge current through an OTA, enabling precise frequency control across load and line conditions.

Its functional architecture includes dual complementary gate drivers (HG/LG) with fixed 380 ns dead time, built-in open-loop/overload protection with extended blanking timer, and independent current sense path with dual thresholds (frequency shift at first threshold, latch-off at second). Mains input voltage sensing (VINS) triggers startup/shutdown with user-adjustable hysteresis via external RC network.

Key Specifications

Parameter	Value and Actual Design Meaning
Topology Support	LLC resonant half-bridge - enables ZVS operation with fixed 380 ns dead time between HG and LG outputs
Min Switching Frequency	25–200 kHz programmable via single RFMIN resistor - sets baseline operating point for PFM regulation
Oscillator Accuracy	±1.5% over -40°C to +125°C - ensures stable frequency setting without trimming components
Gate Drive Outputs	HG and LG with 1 A peak sink/source - directly drives CoolMOS™ half-bridge power stages without external buffers
Current Sense Thresholds	Two-level: 1st level triggers frequency shift for soft current limiting; 2nd level (≈3× I_CS,min) forces immediate latch-off
Soft Start	Digital & nonlinear - limits inrush current and output overshoot by ramping frequency from high initial value to f_min
VINS Protection Hysteresis	Adjustable via external RC - defines turn-on/turn-off voltage window for brown-out immunity

Pinout & Package

ICE1HS01G1XUMA1 is housed in PG-DSO-8 (SOIC-8) package, thermally enhanced with exposed pad for improved power dissipation in high-frequency SMPS designs.

Pin/Terminal	Circuit Role	Design Meaning
FMIN	Minimum frequency programming	1.5 V reference sink - sets f_min via external resistor; also influences max frequency and soft start behavior
CS	Primary-side current sense input	Two-comparator interface - first threshold initiates frequency shift; second triggers latch-off for fault shutdown
FB	Optocoupler feedback input	OTA-based regulation node - 0.9–3.9 V range controls oscillator charge current to adjust switching frequency
VINS	Mains input voltage monitor	Resistive divider input - enables brown-in/brown-out detection with user-defined hysteresis timing
GND	Signal and power ground	Common reference for all analog and digital blocks; connects to PCB thermal pad for thermal management
LG	Low-side MOSFET gate driver	1 A peak drive capability - directly interfaces with low-side CoolMOS™ switch in half-bridge leg
HG	High-side MOSFET gate driver	1 A peak drive with bootstrap supply support - drives high-side switch with integrated dead-time control
VCC	IC power supply input	Operates from 10–20 V - powers internal logic, drivers, and bias circuits; includes UVLO protection

Key Features

Feature	Design Value
Programmable f_min with single resistor	Eliminates need for multiple timing components - reduces BOM count and layout complexity in LLC designs
Two-level overcurrent protection	Enables graceful power limiting before hard fault - improves system reliability during short-circuit or overload transients
Digital nonlinear softstart	Prevents transformer saturation and output overshoot - avoids need for external soft-start circuitry or manual tuning
Integrated mains undervoltage protection	Supports wide-input AC-DC adapters - eliminates external supervisor IC for brown-out detection and recovery
Fixed 380 ns dead time	Guarantees safe commutation in half-bridge - prevents shoot-through without requiring external timing networks

Equivalent & Alternatives

The following parts are listed as comparable options for similar half-bridge resonant controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
UCC256301 (Texas Instruments)	Includes integrated high-voltage startup, X-capacitor discharge, and adaptive dead-time control - no external VCC auxiliary supply needed.	Better suited for cost-sensitive consumer adapters where BOM reduction is critical; lacks adjustable VINS hysteresis.	Select when eliminating auxiliary winding or simplifying startup sequence is prioritized over fine-grained brown-out hysteresis tuning.
IR3584M (Infineon, legacy)	Fixed 100–500 kHz frequency range; no FMIN programming - uses external crystal or RC oscillator with lower accuracy (±5%).	Targeted at fixed-frequency resonant designs; less flexible for wide-output-range or multi-standard adapters.	Choose only for legacy redesigns where frequency stability requirements are relaxed and existing crystal infrastructure exists.

Compared with UCC256301 and IR3584M, ICE1HS01G1XUMA1 offers superior oscillator accuracy (±1.5% vs ±5%), fully programmable f_min, and dedicated VINS hysteresis tuning - making it optimal for high-efficiency, wide-input industrial and premium consumer SMPS where regulation precision and robust line monitoring are essential.

FAQ

What is the purpose of the FMIN pin, and how does it affect operation?

The FMIN pin sets the minimum switching frequency (25–200 kHz) via an external resistor that sinks a precise 1.5 V reference current. This current determines the base oscillator charge rate, which establishes the lowest operating frequency and influences maximum frequency and soft start behavior. It replaces complex RC timing networks with a single, accurate, temperature-stable programming element.

How does the two-level overcurrent protection work in practice?

At the CS pin, the first threshold (≈1× I_CS,min) triggers frequency increase to limit resonant current - a soft, reversible response. If current exceeds the second threshold (≈3× I_CS,min), the IC latches off immediately and requires restart via VCC cycling or VINS re-detection. This dual-stage approach prevents nuisance tripping while ensuring fail-safe shutdown during hard faults like shorted secondary windings.

Can ICE1HS01G1XUMA1 operate without an auxiliary VCC supply?

No - ICE1HS01G1XUMA1 requires a regulated 10–20 V VCC supply derived from an auxiliary winding or startup circuit. Unlike some newer controllers, it lacks high-voltage startup capability. The VCC pin must be powered before HG/LG drivers activate, and UVLO (typically 9.5 V turn-on, 8.5 V turn-off) ensures clean initialization and fault recovery.

What is the role of the VINS pin beyond basic undervoltage detection?

VINS serves three functions: (1) enables startup when mains-derived voltage exceeds VINSON (~1.2 V); (2) shuts down during brown-out when voltage falls below VINSON; and (3) sets auto-restart delay during overload via external capacitor - allowing adjustable hold-off time before soft start re-initiation. Its hysteresis is tuned independently via resistor divider ratio and capacitor value.
