Product details
Overview
LT1162CSW#TRPBF from Analog Devices (formerly Linear Technology) is a dual high-voltage N-channel power MOSFET driver IC for half-bridge and full-bridge topologies. It integrates two independent gate drivers, supports up to 60V floating top-side operation, delivers 1.5A peak output current, features adaptive nonoverlapping logic to prevent shoot-through, and operates from 10V to 15V supply with TTL/CMOS-compatible inputs - used in synchronous buck regulators and brushless DC motor drives.
For engineers reviewing the LT1162CSW#TRPBF datasheet, LT1162CSW#TRPBF pinout, LT1162CSW#TRPBF application, or LT1162CSW#TRPBF equivalent, key selection criteria include bootstrap-capable high-side drive capability, guaranteed shoot-through prevention via internal lockout timing, undervoltage lockout with hysteresis on both V+ and VBOOST, and SO Wide 24-pin package compatibility with industrial temperature range (–40°C to 85°C).
Technical Context
The LT1162CSW#TRPBF implements two fully independent driver channels, each with separate IN TOP/IN BOTTOM inputs, T GATE DR/B GATE DR outputs, and dedicated feedback pins (T GATE FB/B GATE FB) that monitor gate-to-source voltage to enforce sequencing. Its adaptive nonoverlapping logic ensures one MOSFET is fully turned off before the other turns on - eliminating external dead-time circuitry.
Each channel uses a bootstrap architecture: the top driver's floating supply is generated via BOOST–T SOURCE, while the bottom driver uses PV+ referenced to PGND. Undervoltage protection operates independently on main supply (V+) and boost supply (VBOOST – T SOURCE), with 0.5V hysteresis and open-collector UV OUT assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 10V to 15V - ensures stable operation across standard industrial DC rails without external regulation |
| Floating Top-Side Voltage | Up to 60V - enables direct driving of high-side N-MOSFETs in buck, half-bridge, and motor control topologies |
| Peak Output Current | 1.5A (<10µs) - sufficient to rapidly charge/discharge gate capacitance of multiple paralleled MOSFETs |
| Top Gate Rise/Fall Time | 130ns/60ns (typ.) into 3000pF - supports PWM switching up to ~100kHz with low transition loss |
| Undervoltage Lockout Thresholds | V+ start-up: 8.9V, shutdown: 8.3V; VBOOST–TSOURCE start-up: 9.3V, shutdown: 8.7V - prevents partial turn-on during brown-out |
| Input Logic Levels | VIL ≤ 0.8V, VIH ≥ 2.0V - compatible with 3.3V/5V microcontrollers and PWM controllers without level-shifting |
| Operating Temperature | –40°C to +85°C - qualified for industrial motor drives and power supplies with ambient thermal stress |
Pinout & Package
LT1162CSW#TRPBF is housed in a 24-pin SO Wide (SW) surface-mount package with 0.300-inch body width and 0.025-inch lead pitch. Pin assignments are mirrored per channel (A and B), enabling dual half-bridge or single full-bridge implementation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SV+ (Pins 1, 7) | Main signal supply input | Provides bias for logic and level-shifting circuitry; must be decoupled to GND A/B with 10µF capacitor |
| IN TOP A/B (Pins 2, 8 / 14, 20) | Top driver enable input | TTL/CMOS-compatible; disables top driver when corresponding IN BOTTOM is high |
| IN BOTTOM A/B (Pins 3, 9 / 15, 21) | Bottom driver enable input | TTL/CMOS-compatible; disables bottom driver when corresponding IN TOP is high |
| UV OUT A/B (Pins 4, 10 / 16, 22) | Open-collector undervoltage flag | Sinks current when V+ or VBOOST–TSOURCE falls below threshold - used for system fault signaling |
| GND A/B (Pins 5, 11 / 17, 23) | Signal ground reference | Separate low-noise return for logic; must be routed separately from power grounds |
| B GATE FB A/B (Pins 6, 12 / 18, 24) | Bottom gate voltage feedback | Direct connection to MOSFET gate; inhibits top driver until gate discharges below 2.5V |
| T GATE FB A/B (Pins 16, 22 / ?) | Top gate voltage feedback | Direct connection to top MOSFET gate; inhibits bottom driver until VTGFB–VTSOURCE < 2.9V |
| T GATE DR A/B (Pins 17, 23 / ?) | High-current top gate drive output | Drives gate through optional series resistor; handles bootstrapped high-side switching |
| B GATE DR A/B (Pins 13, 19 / ?) | High-current bottom gate drive output | Drives low-side N-MOSFET directly referenced to PGND; supports parallel MOSFET configurations |
| BOOST A/B (Pins 18, 24 / ?) | Bootstrap capacitor high-side connection | Connects to high side of bootstrap cap; recharged each time T SOURCE goes low in PWM cycle |
| T SOURCE A/B (Pins 15, 21 / ?) | Top driver return node | Connects to top MOSFET source and low side of bootstrap capacitor; floats up to 60V |
| PV+ A/B (Pins 14, 20 / ?) | Bottom driver supply input | Must tie to same rail as SV+; powers bottom driver stage and internal level shifters |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive nonoverlapping gate drive | Eliminates external dead-time control by monitoring gate feedback pins and enforcing sequential turn-off/turn-on |
| Floating top driver with 60V capability | Enables use of efficient N-channel MOSFETs on high-side without P-channel or isolated supply compromises |
| Dual independent channels in single package | Reduces PCB area and component count vs. two discrete LT1160s; supports H-bridge or dual-phase buck |
| Undervoltage lockout on V+ and VBOOST | Prevents erratic switching during startup or brown-out by asserting UV OUT and forcing outputs low |
| TTL/CMOS input compatibility with 5V clamp | Accepts 3.3V or 5V logic without external resistors; internal clamping protects against overvoltage transients |

FAQ
What is the maximum floating voltage capability of the LT1162CSW#TRPBF top driver?
The LT1162CSW#TRPBF top driver supports a maximum floating voltage of 60V relative to its T SOURCE pin. This allows direct driving of high-side N-channel MOSFETs in buck, half-bridge, and motor control circuits where the high-voltage rail does not exceed 60V. Exceeding this rating risks permanent damage per Absolute Maximum Ratings.
Does the LT1162CSW#TRPBF require external dead-time circuitry?
No, the LT1162CSW#TRPBF does not require external dead-time circuitry. Its adaptive nonoverlapping logic monitors T GATE FB and B GATE FB pins to ensure one MOSFET is fully turned off before the other turns on. This eliminates shoot-through risk without external timing components - a core design feature confirmed in the Functional Diagram and Timing Diagram sections of the datasheet.
How does the LT1162CSW#TRPBF handle undervoltage conditions on both supply rails?
The LT1162CSW#TRPBF implements independent undervoltage lockout on both V+ and VBOOST–T SOURCE rails, each with 0.5V hysteresis. When either rail drops below its respective shutdown threshold (8.3V for V+, 8.7V for VBOOST–T SOURCE), the device forces all gate outputs low and asserts UV OUT. This dual-rail protection prevents partial turn-on during brown-out or bootstrap capacitor discharge - a verified behavior documented in Electrical Characteristics and Typical Performance Characteristics.
Can the LT1162CSW#TRPBF drive multiple MOSFETs in parallel per channel?
Yes, the LT1162CSW#TRPBF can drive up to five N-channel MOSFETs in parallel per channel, as confirmed in the Applications Information section. Each channel delivers 1.5A peak current and supports gate charge delivery for combined QG loads. When paralleling, use 10Ω–47Ω gate resistors per MOSFET to suppress high-frequency oscillation, and connect only one B GATE FB or T GATE FB pin to any single gate per channel.
What is the operating temperature range specified for the LT1162CSW#TRPBF?
The LT1162CSW#TRPBF is rated for industrial operation from –40°C to +85°C. This is explicitly stated in the PACKAGE/ORDER INFORMATION table under "LT1162ISW" and confirmed in Absolute Maximum Ratings. The "CSW" suffix denotes the SO Wide package with industrial-grade qualification - distinct from the commercial-grade "CN" variant limited to 0°C–70°C.
