Analog Devices Inc. LTC7001JMSE#PBF

Overview

LTC7001JMSE#PBF from Analog Devices is a fast 150V high-side N-channel MOSFET gate driver IC with internal charge pump, enabling 100% duty cycle operation. It supports input voltages up to 135V (150V abs max), features 1Ω pull-down and 2.2Ω pull-up drivers, 35ns propagation delay, and operates across –40°C to 150°C junction temperature - ideal for automotive-grade static switch and high-voltage load control applications.

For engineers reviewing the LTC7001JMSE#PBF datasheet, LTC7001JMSE#PBF pinout, LTC7001JMSE#PBF application, or LTC7001JMSE#PBF equivalent, key selection considerations include its 10-lead MSOP thermal performance (θJC = 10°C/W), adjustable VCC undervoltage lockout via VCCUV pin, OVLO threshold programmability, BST-TS floating UVLO (3.1V), and compatibility with high-voltage N-channel MOSFETs requiring >10V gate overdrive.

Technical Context

The LTC7001JMSE#PBF integrates a high-voltage level-shifting architecture with a regulated internal charge pump that maintains BST–TS at 12V, enabling indefinite high-side conduction without external bootstrap diode dependency. Its dual-output driver stage separates TGUP (P-ch, 2.2Ω) and TGDN (N-ch, 1Ω) for independent slew rate control during turn-on/turn-off.

Protection logic includes three independent undervoltage lockouts: VCCUV-configurable VCC UVLO (3.5V–10.5V), OVLO-pin-based input overvoltage detection (1.11V–1.21V threshold), and BST–TS floating UVLO (3.1V). All lockouts force TGDN to TS, ensuring fail-safe shutdown under fault conditions.

FAQ

What is the maximum allowable TS voltage for LTC7001JMSE#PBF?

The LTC7001JMSE#PBF supports TS voltages from –6V to +150V absolute maximum. Its level-shifting architecture and charge pump allow operation with TS referenced to high-voltage rails up to 135V continuous. The –6V lower limit accommodates inductive kickback during MOSFET turn-off, and the device remains functional within its –40°C to +150°C junction range under these conditions. Always ensure external components (e.g., Schottky diode from TS to GND) are rated for the full TS excursion range when used.

How does the internal charge pump in LTC7001JMSE#PBF enable 100% duty cycle operation?

The LTC7001JMSE#PBF internal charge pump actively regulates the BST–TS voltage to 12V, independent of TS potential. Unlike passive bootstrap circuits that collapse during sustained high-side conduction, this regulated pump replenishes BST–TS charge continuously - allowing the TGUP driver to maintain full gate enhancement on the external N-channel MOSFET indefinitely. This eliminates reliance on external diodes or complex timing constraints, making LTC7001JMSE#PBF suitable for static switch applications where the MOSFET must remain fully on for extended periods without interruption.

Can LTC7001JMSE#PBF drive a MOSFET with 50nC gate charge?

Yes, the LTC7001JMSE#PBF can reliably drive MOSFETs with up to ~50nC total gate charge. Its 1Ω pull-down and 2.2Ω pull-up drivers deliver >1A peak current into typical loads, achieving <50ns rise/fall times with 1nF capacitance. For a 50nC MOSFET, gate drive energy is supplied by the BST–TS 12V rail and external 0.1µF capacitor; the internal charge pump's 30µA output sustains BST–TS under moderate switching frequencies (<500Hz). At higher frequencies or larger Q_G, adding an external silicon diode from VCC to BST (per Figure 3 in datasheet) ensures sufficient recharge current.

What is the purpose of the NC pin (Pin 10) on LTC7001JMSE#PBF?

Pin 10 of the LTC7001JMSE#PBF is designated NC (No Connect) and has no internal connection. It must remain electrically floating - neither tied to GND, VCC, nor any other node. This pin exists for mechanical symmetry and package compatibility; routing traces or placing vias to Pin 10 may cause unintended coupling or violate layout rules. The exposed thermal pad (Pin 11) and Pins 1–9 carry all functional signals; Pin 10 serves no electrical role in the LTC7001JMSE#PBF operation.

How is the VCC undervoltage lockout threshold set on LTC7001JMSE#PBF?

The VCC undervoltage lockout (UVLO) threshold on LTC7001JMSE#PBF is set using the VCCUV pin (Pin 2). An external resistor from VCCUV to GND forms a divider with an internal 10µA current source, generating a reference voltage. The rising UVLO threshold equals 7 × (V_VCCUV); thus, a 100kΩ resistor yields ~7.0V UVLO. If VCCUV is left open, the internal default is 7.0V. The falling threshold includes hysteresis (~600mV), and the full adjustable range is 3.5V to 10.5V - ensuring stable gate drive enablement only when VCC is sufficiently regulated for reliable operation of LTC7001JMSE#PBF.
