SA1002 Datasheet SA1002 (APM) 80 V Full-bridge or Dual Half-bridge Protected Driver IC Device Overview The SA1002 (APM) is a full-bridge or dual half- Two precision voltage dividers (+/-0.5%) with 80 bridge driver IC dedicated to control 4 N-channel V maximum input voltage and program-mable MOSFETs typically forming the DC/DC converter division ratios (1/64, 1/32, 1/16, 1/8) stage in industrial/telecom power supplies, battery Three fast voltage dividers (20 MHz) with 80 V inverters and chargers, and PV micro-inverters. The maximum input voltage and programmable division device is rated for harsh environments and is rated ratios (1/64, 1/32, 1/16, 1/8) for 80 V operation. Pseudo-differential analog interface for divider It incorporates integrated hardware for voltage outputs or ground-references, or direct or buffered sensing, a 2 W flyback controller (for system self- divider output options power), 2 pairs of high-side and low-side MOSFET Flyback controller with 0.5 ohm /90 V switch and drivers. It also included critical protection features soft-switching controller like: programmable UVLO, temp sensor, and 5 V minimum start-up voltage for 300 mW load cross-conduction protection functions for each Two 3 V / 50 mA low drop-out linear voltage driver pair. The device is easily programmed via regulators 2 industry-standard I C interface. 2 mA / 2.8 V linear regulator with up to 80 V input Temperature sensor APM Key Features 2 I C interface (slave) Dual 12 V / 2.5 A low-side drivers with program- TQFP48 exposed-pad package mable under-voltage lock out (UVLO) Dual 12 V/0.5 A high-side drivers with Applications programmable UVLO Battery and fuel cell inverters (bi-directional) Integrated MOSFET driver cross-conduction Dual phase DC/DC power supply protection (driver interlock) DC-DC power optimizers SA1002 (APM) block diagram Solantro Semiconductor Corp.
