Product details
Overview
HR1000AGS-Z from Monolithic Power Systems is a resonant half-bridge controller IC designed for high-efficiency AC-DC and DC-DC power conversion. It delivers complementary 50% duty-cycle gate drive signals with 350 ns fixed dead-time, supports up to 600 kHz switching frequency, integrates a 600 V high-side driver with bootstrap diode, and provides 1.5 A/2 A source/sink capability for both high-side (HG) and low-side (LG) MOSFETs - deployed in LCD TV and telecom SMPS front-end stages.
For engineers reviewing the HR1000AGS-Z datasheet, HR1000AGS-Z pinout, HR1000AGS-Z application, or HR1000AGS-Z equivalent, key selection criteria include resonant topology compatibility, 600 V floating gate-driver rating, programmable burst-mode threshold, dual-level over-current protection (frequency-shift + latched shutdown), and PFC disable interface timing behavior.
Technical Context
The HR1000AGS-Z implements a current-mode-controlled oscillator where CT capacitor charge/discharge-modulated by Fset pin reference current-sets switching frequency between 50 kHz and 600 kHz. Its internal 2 V reference at Fset enables opto-coupler feedback integration for output voltage regulation via frequency modulation.
It features two independent protection paths: a fast frequency-shift response triggered at CS ≥ 0.8 V (with 50 mV hysteresis) and a latched shutdown at CS ≥ 1.5 V; BO pin provides non-latching brown-out detection at 1.25 V with 12 µA hysteresis current, while LATCH pin enables external system-level fault latching at 1.85 V threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology Support | Resonant half-bridge only - requires ZVS operation and precise dead-time control. |
| Max Switching Frequency | 600 kHz - enables compact magnetics and high-power-density designs in <200 W applications. |
| Gate Drive Capability | 1.5 A source / 2 A sink per channel - sufficient to drive 10–25 nC MOSFETs at ≤600 kHz without external buffers. |
| High-Side Voltage Rating | 600 V BST/SW - supports direct integration with 600 V MOSFETs in universal-input AC-DC converters. |
| Oscillator Accuracy | ±5% over temperature - ensures stable frequency set-point for EMI compliance and thermal management. |
| Over-Current Protection | Dual-level: frequency shift at 0.8 V CS, latched shutdown at 1.5 V - prevents transformer saturation and MOSFET failure. |
| Burst-Mode Threshold | 1.23 V nominal on BURST pin - enables light-load efficiency optimization below ~10% load without audible noise. |
Pinout & Package
HR1000AGS-Z is housed in a SOIC-16 (SO-16) package with creepage-enhancing NC pin (Pin 13) and isolated high-voltage layout for BST/SW/HG domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SS | Soft-start timing node | Controls startup frequency ramp via external RC; discharges internally during fault conditions to enforce monotonic VOUT rise. |
| 2 TIMER | Over-current duration timer | Charged by 130 µA current during OCP; triggers forced max-frequency mode at 2 V and latched shutdown at 3.5 V. |
| 3 CT | Oscillator timing capacitor node | Triangular waveform generator - peak (3.8 V) and valley (0.9 V) thresholds define switching period. |
| 4 Fset | Frequency-set reference input | 2.0 V ±4% internal reference; sets min/max frequency via resistor network and opto-coupler feedback current. |
| 5 Burst | Burst-mode enable threshold | Enters low-power idle state when voltage drops below 1.23 V; resumes at 1.28 V with no soft-start reinitiation. |
| 6 CS | Primary current sense input | Monitors half-bridge primary current via sense resistor; initiates frequency-shift OCP at 0.8 V and latch at 1.5 V. |
| 7 BO | Brown-out detection input | Shuts down non-latching at 1.25 V; includes 12 µA hysteresis current source and internal Zener clamp at 5.5 V. |
| 8 LATCH | External fault latching input | Latches off entire IC when voltage exceeds 1.85 V; requires VCC UVLO cycle to reset. |
| 9 PFC | PFC controller disable output | Drives PFC IC low during burst-mode, OCP, OTP, BO fault, or TIMER > 2 V - reduces system standby loss. |
| 10 GND | Signal and low-side return | Common reference for bias, CS, BO, LATCH, and LG driver - must be star-connected to minimize noise coupling. |
| 11 LG | Low-side gate driver output | 1.5 A/2 A drive into MOSFET gate; actively pulled to GND during UVLO for safe turn-off. |
| 12 VCC | IC supply input | Operates from 8.9–15.5 V; includes 11 V turn-on / 8.2 V turn-off UVLO with 2.5 V hysteresis. |
| 13 N.C. | High-voltage isolation spacer | No internal connection - maintains >5.5 mm creepage between SW and GND pins per IEC 60950-1. |
| 14 SW | High-side switch source node | Floating ground return for HG driver; withstands −3 V to VBST−18 V with 50 V/ns dV/dt immunity. |
| 15 HG | High-side gate driver output | 1.5 A/2 A drive referenced to SW; internal pull-down ensures safe default state during UVLO. |
| 16 BST | Bootstrap supply input | Connects to SW via external capacitor; fed by integrated bootstrap diode synchronized with LG switching. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | Eliminates external diode in high-side drive path - reduces BOM count and layout area in SO-16 footprint. |
| Programmable burst-mode entry | Configurable via resistor divider on BURST pin - enables sub-100 mW no-load consumption in AC-DC adapters. |
| Two-level over-current response | Frequency-shift (soft) followed by latched shutdown (hard) - balances reliability and transient recovery in resonant systems. |
| PFC disable interface | Active-low open-drain output on PFC pin - synchronizes PFC stage shutdown with HR1000AGS-Z fault events. |
| Non-linear soft-start | Exponential SS capacitor charging - prevents output overshoot and inrush current in high-capacitance hold-up designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar resonant half-bridge controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC256301DR | Fixed 500 kHz max frequency; no integrated bootstrap diode; requires external high-side driver bias. | Targeted at cost-sensitive consumer PSUs - lacks BO and PFC-disable pins, limiting use in industrial telecom. | Select UCC256301DR only if bootstrap diode omission is acceptable and PFC coordination is unnecessary. |
| ICE2HS01G | Higher 1.2 A/1.5 A gate drive; no burst-mode; single-level OCP only; SO-14 package. | Designed for lower-power (<100 W) lighting ballasts - lacks TIMER pin for programmable OCP duration. | Choose ICE2HS01G for simpler lighting designs where burst-mode and dual OCP are not required. |
Compared with UCC256301DR and ICE2HS01G, HR1000AGS-Z uniquely combines 600 V high-side drive integrity, integrated bootstrap diode, programmable burst-mode, and PFC disable signaling - making it optimal for high-reliability, multi-stage AC-DC systems requiring coordinated protection.

FAQ
What is the maximum allowable dV/dt on the SW pin?
The SW pin withstands up to 50 V/ns dV/dt without false triggering or latch-up, verified per Absolute Maximum Ratings table. This immunity enables robust operation with fast-switching 600 V MOSFETs or GaN devices in high-frequency resonant converters without additional snubbing.
Can HR1000AGS-Z drive GaN HEMTs directly?
Yes - its 1.5 A/2 A gate drive strength, 20 ns rise/fall times, and 600 V floating capability meet typical GaN HEMT gate requirements (Qg ≈ 5–15 nC). Layout must minimize SW/HG loop inductance and use Kelvin-source connections for optimal switching performance.
How does the TIMER pin implement delayed shutdown?
Pin 2 charges at 130 µA during over-current events. At 2 V, it forces maximum frequency; at 3.5 V, it disables switching and turns off the current source. Discharge via external resistor determines timeout - e.g., 100 kΩ + 100 nF yields ~12 ms delay before latched shutdown.
Is the Fset pin's 2 V reference buffered for external use?
No - the 2.0 V reference is unbuffered and intended solely for setting oscillator current. It sinks up to 2 mA but exhibits load-dependent drift beyond 10 µA; do not use it as a system reference voltage source.
What happens to the PFC pin during thermal shutdown?
During thermal shutdown (TJ ≥ 150 °C), the PFC pin is actively driven low to disable the front-end PFC controller - ensuring coordinated system-level protection and preventing thermal runaway in cascaded power stages.
Does HR1000AGS-Z support synchronous rectification?
No - HR1000AGS-Z is a primary-side resonant half-bridge controller only. It does not provide secondary-side gate drive outputs or timing signals for synchronous rectifiers; external SR controller ICs are required for that function.
What is the minimum recommended CT capacitor value?
0.1 nF is the minimum CT value specified for stable operation. Below this, oscillator jitter increases significantly; for low-temperature or high-frequency designs (>400 kHz), MPS recommends ≤330 pF to maintain sufficient Fset pin current drive margin.
